it sent 7 data bytes of the device descriptor instead of the requested 8.
However, the mac then goes into a very strange infinite loop, sending:
SETUP
DATA0(empty)
SETUP
DATA1(empty)
My guess as to what's happening is the enumeration code doesn't check
the length of data returned and assumes it got all 8 bytes. The 8th
byte is the max packet size of endpoint zero, so it sets up endpoint
zero as zero length, you're seeing it send the zero length packets.
It takes a long time to transfer data with a zero max packetsize.
There was a similar bug I put in and later fixed in OS 9 a while ago.
