I have a USB device that has always worked fine in the past, but now I can no longer access it when it is plugged in to my bookworm systems. (I last used the device a couple of weeks ago.)

Once plugged in, lsusb shows it:

----

[ZB:~] lsusb
...
Bus 001 Device 011: ID 0483:a1de STMicroelectronics AA-35 Analyzer
...
[ZB:~]

----

and dmesg shows it appearing on the system:

----

[ 2593.910210] usb 1-1: new full-speed USB device number 11 using xhci_hcd
[ 2594.059907] usb 1-1: New USB device found, idVendor=0483, idProduct=a1de, bcdDevice= 2.00

----

but it no longer appears in lsusb, and I can find no way to access the device 
:-(

Does anyone have any ideas or suggestions for things to do to try to make the device accessible once again?

(As far as I can tell, all other USB devices are working as usual.)
