I can’t figure out how to access USB devices on my VMware ESXi host. I need to connect a USB drive for backup purposes, but it’s not displaying in the storage options. What steps do I need to follow to properly connect and use a USB device in ESXi?
Alright, connecting a USB drive to a VMware ESXi host can be a bit tricky if you’re new to its interface. Here’s a step-by-step guide to help you out.
-
Enable USB Passthrough:
- Log in to your ESXi host using the vSphere Client.
- Go to the ‘Host Settings.’
- Click on ‘Manage’ and then ‘Hardware.’
- Select ‘PCI Devices’ and then click on ‘Configure Passthrough.’
- Check the box for your USB controller and click ‘OK.’
-
Create a Datastore:
- In the left-hand navigation pane, select ‘Storage’.
- Click ‘New Datastore’ and follow the wizard.
- Choose ‘VMFS’ and select your USB device from the list.
- Finish out the wizard to create your new datastore.
-
Add USB to Virtual Machine:
- Right-click on your VM.
- Select ‘Edit Settings.’
- Click on ‘Add New Device’ and choose ‘Host USB Device’.
- From the list, select your USB drive.
Just so you know, if you prefer a hassle-free method to access USB devices over the network, consider using something like FlexiHub. This tool enables remote access to USB devices through the network effortlessly, making it an excellent solution for backup and other purposes.

Hope this helps!
Alright, I see you’re having trouble with USB devices on your VMware ESXi host. Mike34 gave you a solid rundown, but I’d add a couple of points that might help further:
-
Check ESXi Compatibility: Sometimes the USB drive or even the USB controller might not be compatible with VMware ESXi. Make sure your hardware and the ESXi version support USB passthrough. You can find compatibility info on VMware’s HCL (Hardware Compatibility List).
-
Reboot the Host Post-Configuration: After enabling USB passthrough, it might be necessary to reboot the host. This ensures the settings are correctly applied.
-
Check USB Controller Settings: Ensure that your USB controller isn’t in EHCI mode, as ESXi has better support for xHCI.
-
Permissions Issue: Sometimes, the permissions on the USB device can cause issues. Make sure your ESXi user has the right permissions to access USB devices. Also, ESXi has specific configurations for USB arbitrators. You might want to tweak them.
-
ESXi Version Matters: Make sure your ESXi version is up to date. Older versions have bugs and limitations regarding USB passthrough.
Also, just to shed some light on another option. If you are continually struggling with hardware access, consider using tools that facilitate USB over network solutions. FlexiHub is an excellent option for this. With FlexiHub, you can access and manage USB devices over a network, making it straightforward even if your ESXi host doesn’t directly play nice with USB devices.
Hopefully, between Mike34’s steps and these additional tips, you’ll get your USB drive working for your backup needs!
If ll the above didn’t help and it doesn’t show as a device, ESXi might not like the controller/drive combination, or you may need to play with USB passthrough and access it inside a VM instead (attach it as a USB device to a backup VM and back up to it from inside the guest OS).
If you keep fighting with ESXi and USB support, a more reliable option is to plug the drive into another machine (Windows, Linux, etc.) and “virtually” attach it to your backup VM using a USB-over-network tool like USB Network Gate. It shares the physical USB in VMware and makes it appear in the VM as if it were plugged in locally, which avoids all the ESXi host USB quirks.
