Public bug reported:
I'm using Amadeus spectrometer (OceanOptics USB250) via Windows-based
software "Quantum". I've tried six ways of attaching it to QEMU:
1. command line parameter "-device usb-host,hostbus=3,hostaddr=25"
2. command line parameter "-device usb-host,vendorid=0x2457,productid=0x1030"
3. command line parameter "-usbdevice host:2457:1030
4. command line parameter "-usbdevice host:3.25"
5. qemu console command "usb_add host:2457:1030"
5. qemu console command "usb_add host:3.25"
>From these, only "-device ..." options work, i.e. numbers 1 and 2 in the
list above, and all others lead to IRQL_NOT_LESS_OR_EQUAL BSOD in
usbuhci.sys when I launch Quantum, which tries to start acquiring
spectra.
I've also tried to reproduce the crash with a flash drive, but couldn't
— it seems to work reliably in this case.
