Hi, I'm trying to get an S100U that came as part of the dev kit light working. I have tried compiled EHCI as modules or directly into the kernel but the same problem happens both times: I connect the S100U and run modprobe wcusb - initially nothing happens (great - no errors, etc). Fairly soon the server will die. It seem to be related to communications with the S100U. For example if I run "more /proc/zaptel/2" a couple of times the server will hang (BTW before it dies the output of /proc/zaptel/2 is just span = "" - or something very like it - my server is dead again and I was remotely connected to it!). The zaptel module and the X100P module are working fine with asterisk - it seems to be a usb/S100U only problem. I'm running Linux 2.6.7 on a gateway PIII 550Mhz. When the server hangs there is no response at all - network, keyboard, etc and I have to reboot it to get back in (nothing is written to log files either). Has anyone else had problems with the wcusb & S100U hanging their server? Thanks very much, Derek
