Hello,
Thank you for posting in Q&A forum.
Yes, you can transfer USB flash drives to virtual machines through the functionality of Hyper-V. This allows virtual machines to directly access USB devices connected to the host. To achieve this, you need to configure the settings of the Hyper-V host and virtual machine to allow USB device transfer. Then, you can see and use the USB flash drive connected to the host in the virtual machine.
Hope this answer can help you well.
Best regards,
Jill Zhou
