Indeed, the device appears added to the UHCI in both crashing cases and
to EHCI in the working case. Also, sometimes instead of BSOD of guest OS
I get abort of QEMU:
qemu-system-i386: hw/usb/core.c:735: usb_ep_get: Assertion `pid == 0x69 || pid
== 0xe1' failed.
/usr/bin/qemuxp: line 4: 13514 Aborted (core dumped)
qemu-system-i386 /home/ruslan/iso/Windoze/qemuxp.img -m 512 -display sdl -vga
vmware -enable-kvm -usb -device usb-ehci $*
here $* stands for
-snapshot -hdb ~/iso/ntfs-data.img
and the crash was triggered by using usb_add command in QEMU terminal
and then attempting to access the device from WinXP.

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=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.
