you're right: your issues are the same, but BSD doesn't report EOVERFLOW
has it should.
while Dmitry is running on Linux, the patch should work there.

@Robert: could you please run the test again (with wathever version), using
debug level 5 (-DDDDD) and doing "export USB_DEBUG=3" before launching the
driver?

if there is no way to catch overflow on BSD, I fear I'll have to create a
driver option to bypass this...

cheers,
Arno
