I had the time to set up -current (2009-06) on real hardware. Here are
the results:

Running on real hardware (I used do_request directly):

root at mireille:~# usbconfig -u 2 -a 2
ugen2.2: <USBasp www.fischl.de> at usbus2, cfg=0 md=HOST spd=LOW
(1.5Mbps) pwr=ON
root at mireille:~# usbconfig -u 2 -a 2 do_request 0x80 0x06 0x0301 0x0409 256
REQUEST = <0x1c 0x03 0x77 0x00 0x77 0x00 0x77 0x00 0x2e 0x00 0x66 0x00
0x69 0x00 0x73 0x00 0x63 0x00 0x68 0x00 0x6c 0x00 0x2e 0x00 0x64 0x00
0x65 0x00><www.fischl.de>

Compare this to the results from VMware:

freebsd8# usbconfig -u 0 -a 3
ugen0.3: <USBasp www.fischl.de> at usbus0, cfg=0 md=HOST spd=FULL
(12Mbps) pwr=ON
freebsd8# usbconfig -u 0 -a 3 do_request 0x80 0x06 0x0301 0x0409 256
REQUEST = <0x2e 0x00 0x66 0x00 0x69 0x00 0x73 0x00 0x63 0x00 0x68 0x00
0x6c 0x00 0x2e 0x00 0x64 0x00 0x65 0x00><.fischl.de>


Within VMware the first bytes from the response are missing! The only
difference I can see is the speed being LOW vs FULL (where LOW is correct).

I give up on this. And remember that VMware and FreeBSD don't play well
with USB devices.

Thanks so far!
