Fixes for USB Flash Drive Not Recognized/Detected
If you're not in one of the scenarios above, you can also apply the tips detailed below to have a try.
Fix 1. Recover Files from RAW USB Drive before Formatting
Applies to: Fix USB becomes RAW.
There must be file system errors on your USB flash drive that make your USB device not recognized as RAW. It could be file system missing, corrupted, or not compatible with Windows.
To repair a RAW USB, all you need to do is to recover data from the USB that is not recognized and then convert RAW to NTFS or FAT32 file system by formatting. Formatting will erase the existing data on your USB stick. That's why you need to perform data recovery first.
To retrieve data from an inaccessible device, you can use the professional disk recovery software - EaseUS Data Recovery Wizard. It perfectly supports deleted file recovery, formatted data recovery, RAW partition recovery, and other data loss situations.
To recover data from the RAW USB:
Step 1. Choose the flash drive to scan.
Launch EaseUS Data Recovery Wizard and choose your flash drive where you lost important files. Click 'Scan' to start.
Step 2. Check and preview found flash drive data.
After the scanning is finished, you can quickly locate a specific type of file by using the Filter feature as well as the Search.

- Search: e.g. File name/file extension.
Step 3. Restore flash drive data.
After checking and finding lost flash drive files, select them and click Recover to restore. You shall save the found files to a safe location on your PC rather than to your flash drive.
After retrieving all the files, you can now format the USB flash drive and assign a new file system to the device, which will make it usable again.
Fix 2. Update Unallocated USB Driver and Create New Partition
Applies to: Fix USB shows as unallocated space.
If your USB is not recognized by the computer and becomes unallocated space, it probably results from outdated USB driver. Thus, you should try to reinstall the USB device driver.

Step 2. Navigate to 'Control Panel' > 'System' > ‘’Device Manager' > 'Disk drivers'.
Step 3. Find and select your USB device, right-click and first choose 'Uninstall' and then choose 'Scan for hardware changes' to refresh the drivers.
Step 4. Restart your computer.
After all the operations, you may find USB not recognized issue is fixed and the flash drive is detected. If reinstalling the USB driver doesn't help, you can recover data from the unallocated space with EaseUS Data Recovery Wizard introduced above and then create a new volume to make it ready for data storage. (The unallocated space will show up as 'lost partition' in EaseUS data recovery software. Choose the right partition to scan and then recover your data.)
To create a new volume on unallocated space:
Step 1. Go to 'This PC', right-click it and choose 'Manage' > 'Disk Management'.
Step 2. Right-click the unallocated space and choose 'New Simple Volume'.
Step 3. Follow the wizard to finish the remaining process.
Fix 3. Change USB Driver Letter to Make It Detectable
Applies to fix: USB shows without driver letter.
Another reason for USB flash drive not detected issue is that the drive letter assigned to the USB drive is occupied by another drive on the computer (or the drive letter on the USB is missing). To solve this problem, you just need to try EaseUS free partition software to assign an unused drive letter to the USB flash drive. It will help you fix the 'USB flash drive not recognized' issue and recover all the inaccessible data with ease.
You can also assign a drive letter to your USB in Disk Management.
Step 1. Keep your USB connected. Right-click 'This PC' and choose 'Manage' > 'Disk Management'.

Features Documentation Knowledge Base Discussion Forums
The following sections describe how to use USB devices in a virtual machine:
VMware Workstation 4 provides a two-port USB 1.1 controller. You can use up to two USB devices in your virtual machine if both your host operating system and your guest operating system support USB. If your host computer supports USB 2.0 devices, you can use those devices in the virtual machine.
Note: Windows NT and Linux kernels older than 2.2.17 do not support USB.
Although your host operating system must support USB, you do not need to install device-specific drivers for your USB devices in the host operating system if you want to use those devices only in the virtual machine.
On a Windows 2000 host computer with USB 2.0 support, be sure you are using the Microsoft USB 2.0 driver for the USB controller. Third-party USB 2.0 drivers, such as those provided by some motherboard manufacturers, are not supported. For notes on replacing the third-party drivers, see Replacing USB 2.0 Drivers on a Windows 2000 Host.
We have tested a variety of USB devices with this release. In general, if the guest operating system has appropriate drivers, you should be able to use PDAs, printers, storage (disk) devices, scanners, MP3 players, digital cameras and memory card readers.
Modems and certain streaming data devices, such as speakers and Web cams, do not work properly.
The virtual machine's USB ports are enabled by default. If you will not be using USB devices in a virtual machine, you can disable its USB controller using the virtual machine settings editor.
When a virtual machine is running, its window is the active window and a USB device is plugged into the host computer, the device automatically connects to the guest instead of the host. This autoconnect feature can be disabled in the USB Controller panel of the virtual machine settings editor (VM > Settings). If all of the virtual machine's USB ports are already occupied when it is trying to connect automatically to a new device, a dialog box gives you a choice: you can either disconnect one of the existing USB devices to free its port or ignore the new device, allowing the device to connect to the host.
Choose VM > Removable Devices to connect specific USB devices to your virtual machine. You can connect up to two USB devices at a time. If the physical USB devices are connected to the host computer through a hub, the virtual machine sees only the USB devices, not the hub.
There is a menu item for each of the USB ports. Move the mouse over one of these items to see a cascading menu of devices that are plugged into your host computer and available for use. To connect a device to the virtual machine, click its name.
If a device is already connected to that port, click the name of a new device to release the first device and connect the new one.
To release a connected device, click None on the cascading menu for the port to which it is connected.
If you physically plug a new device into the host computer and the autoconnect feature does not connect it to a virtual machine, the device is initially connected to the host. Its name is also added to the VM > Removable Devices menu so you can connect it to the virtual machine manually.
Windows 2000, Windows XP and Windows Server 2003 hosts: When a particular USB device is connected to a virtual machine for the first time, the host detects it as a new device named VMware USB Device and installs the appropriate VMware driver.

Windows XP and Windows Server 2003 hosts: User confirmation is required in the Found New Hardware Wizard. Select the default action — Install the software automatically. Once the software is installed, the guest operating system detects the USB device and searches for a suitable driver.
When you are synchronizing a PDA, such as a Palm handheld or Handspring Visor, to a virtual machine for the first time, the total time required to load the VMware USB device driver in the host and the PDA driver in the guest may exceed the device's connection timeout value. This causes the device to disconnect itself from the computer before the guest can synchronize with it. If this occurs, let the guest finish installing the PDA driver, dismiss any connection error warnings, then try synchronizing the PDA again. The second attempt should succeed.
To use VMware Workstation 4 on a Windows 2000 host that has USB 2.0 ports, you must use the Microsoft USB 2.0 drivers for the USB controller in the host operating system. If your host operating system is using a third-party driver — a driver supplied by your motherboard vendor, for example — you must replace it.
Take the following steps to check the provider of your driver:
- Go to the Device Manager. Right-click My Computer, choose Properties, click the Hardware tab, then click Device Manager.
- Expand the listing for Universal Serial Bus controllers.
- Right-click the listing for the controller and choose Properties.
- Click the Driver tab. If the driver provider shown on that page is Microsoft, you have the correct driver already.
If the driver provider is not Microsoft, download the latest USB driver for your host operating system from the Microsoft Web site and follow the Microsoft instructions to install it. Details are available in Microsoft knowledge base article 319973.
Any user on a Windows host can connect USB devices for use in a virtual machine. You no longer need administrative privileges on the host to connect a USB device to a virtual machine.
This functionality is not enabled by default. To enable it, you must use a text editor such as Notepad to add one line to the global configuration file. This file is
C:Documents and Settings<username>Application DataVMwareconfig.ini
Add the following line anywhere in the file:
usb.EnablePnpMgr = TRUE
Note: A user with administrative privileges on the host operating system must install a USB device on the host before it can be connected by users who do not have administrative privileges.
On Linux hosts, VMware Workstation uses the USB device file system to connect to USB devices. In most Linux systems that support USB, the USB device file system is at /proc/bus/usb. If your host operating system uses a different path to the USB device file system, you can change it in the virtual machine settings editor (VM > Settings > USB). Enter the correct path in the Path to usbdevfs field.
Only one computer — host or guest — can have control of a USB device at any one time.
When you connect a device to a virtual machine, it is 'unplugged' from the host or from the virtual machine that previously had control of the device. When you disconnect a device from a virtual machine, it is 'plugged in' to the host.

Caution: On Windows 2000, Windows XP and Windows Server 2003 hosts, you need to take a special step to disconnect USB network and storage devices from the host. There is a system tray icon called Eject Hardware on Windows 2000 and Safely Remove Hardware on Windows XP and Windows Server 2003. Use this icon to disconnect the device from the host before connecting it to a virtual machine.
Note: On Windows 2000, Windows XP and Windows Server 2003 hosts, when you connect a USB network or storage device in a virtual machine, you may see a message on your host that says the device can be removed safely. This is normal behavior, and you can simply dismiss the dialog box. However, do not remove the device from your physical computer. VMware Workstation automatically transfers control of the device to the virtual machine.
Under some circumstances, if a USB storage device is in use on the host (for example, one or more files stored on the device are open on the host), an error appears in the virtual machine when you try to connect to the device. You must let the host complete its operation or close any application connected to the device on the host, then connect to the device in the virtual machine again.
On Linux hosts, guest operating systems can use devices that are not already in use by the host — that is, devices that are not claimed by a host operating system driver.
If your device is in use by the host and you try to connect it to the guest using the VM > Removable Devices menu, a dialog box appears, informing you that there is a problem connecting to the device.

To disconnect the device from the host, you must unload the device driver. You can unload the driver manually as root (su) using the rmmod command. Or, if the driver was automatically loaded by hotplug, you can disable it in the hotplug configuration files in the /etc/hotplug directory. See your Linux distribution's documentation for details on editing these configuration files.
A related issue sometimes affects devices that rely on automatic connection (as PDAs often do).
If you have successfully used autoconnection to connect the device to your virtual machine, then experience problems with the connection to the device, take the following steps:
- Disconnect and reconnect the device. You can either unplug it physically, then plug it back in or use the VM > Removable Devices menu to disconnect it and reconnect it.
- If you see a dialog box warning that the device is in use, disable it in the hotplug configuration files in the /etc/hotplug directory.
Before unplugging a USB device or using the VM > Removable Devices menu to disconnect it from a virtual machine, be sure it is in a safe state.
You should follow the procedures the device manufacturer specifies for unplugging the device from a physical computer. This is true whether you are physically unplugging it, moving it from host to virtual machine, moving it between virtual machines or moving it from virtual machine to host.
