[qubes-users] Qubes not reading flash drive

I have a Sandisk Cruzer 8GB flash drive with some older documents on it that I need to access, when I plug it in to Qubes it shows up in the available devices but when I connect it to any appvm it is not showing up in the file manager. Other newer flash drives work fine.
Any way to get the system to read it?

File managers will only see a whole disk that is passed to the VM,
not a single partition. Are you passing the whole disk?

I have several Sandisk Ultra_Fit 32Gb which refuse to even be seen by my sys-usb (fedora-32 based template) but works just fine passing the device if I were to use dom0, which obviously I don’t like to do but the devices are useless otherwise.

Are you using a sys-usb vm with its own controller? What templates are you using?

I am using sys-usb on a laptop.

And I have to say that I have some usb devices also that do not work
properly in Qubes. I even have one device that is only
visible on one particular old Windows laptop and on nothing else. USB
seems to be very "flexible" in its implementation.

I have been thinking about setting up a RaspberryPie to use as a USB
interface, and using that to do the upload/download from the usb devices
and copy across the network. Something to do while in lockdown maybe.

Best of luck,
