Hi,
Disconnecting a GPRS modem (cdc-acm, compiled as module) from an iBook G4
running 2.6.1-ben1 gives the following log:
usb 4-1: USB disconnect, address 3
Badness in ohci_endpoint_disable at drivers/usb/host/ohci-hcd.c:334

pppd hangs and does not exit after sending it a SIGHUP, too. I don't know if
this is related...
