And this is the same since much earlier (about a year older) version. And of course I do enable EHCI controller via `-device usb-ehci`. And checked it with native Windows XP, where the device works with no problem. Actually, as I said in OP, `-device hsb-host,...` options work in QEMU too, but the others like `-usbdevice host...` and `usb_add host...` don't. -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1440843 Title: Guest WinXP crashes when trying to use a USB spectrometer Status in QEMU: New Bug description: 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=3D3,hostaddr=3D25" 2. command line parameter "-device usb-host,vendorid=3D0x2457,productid= =3D0x1030" 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 =E2=80=94 it seems to work reliably in this case.
