Hi,

I've been spending quite a bit of time lately getting my little usb-to-usb network
to work (using usbnet.c). I evertually got it working with the help of
people from this list (thanks again), and thought I'd share my findings.

System: 2.4.18 on both systems, with pentium-class CPU's.

I've tried so far 3 cables (fourth on it's way), and I could not get any to work
properly, until I compiled the kernel with the other of the 2 available UHCI drivers.
For some reason I had initially selected the UHCI_ALT driver, and it proved to be 
the root of my problems. When I changed to UHCI, things looked much better (not 
perfect though)

*cable 1, based on Prolific PL2302 (Vendor:067b, prodID:0001)
does not work with either UHCI driver. when hotplugged things 
look fine, /proc/bus/usb/devices/ provides the right info, but 
I can not ifconfig usb0. It always throws the following error:
SIOCSIFFLAGS: Broken Pipe

*cable 2, Genesys logic GL620USB (GeneLink) (Vendor:05e3, prodID:0502)
does not work properly with UHCI_ALT driver. when hotplugged things 
look fine, /proc/bus/usb/devices/ provides the right info, ifconfig usb0
works ok also, but the connection is very very slow, with packets being constantly 
dropped (ping throws a packet loss of te order of +90%. 
However, it works fine if I compile UHCI driver

*cable 3, again based on Prolific, but PL2301 chip (Vendor:067b, prodID:0000)
same as with cable 2

I am curently expecting a Belkin cable to try and compare.

Hope it is of help to somebody out there. Ta.

Jaime
