USB Flash memory stick

Hi,
My Mass storage class driver (on the host side) has to support the
access to "USB flash memory stick device".
Do I need to support both "bulk-only" and "control_bulk_interrupt"?

suggestions please.

Thanks in advance.

It depends upon the particular "USB flash memory stick device"
that you are using. This "protocol" information is found
in one of the descriptors (device?), which you can examine
using an system specific tools while the device is plugged
into a PC.

Under Linux, you can use the "lsusb" command to look at the
descriptors.

Is there a similar tool to use under XP?

I think there are some windows based tools like CATC USBTracer, HHD USB
Monitor e.t.c, but i never used them for this purpose.
