Never looked into it; but the "line 2650" error is always there... even with no devices or USB/PCMCIA plugged in; only the builtin USB port... The timeouts have always been there with no apparent impact; though when the printer is not connected or does not work, those lines are not there... so I suspect they are from the printer ------ confirmed with only printer connected to builtin. BTW, the builtin is UHCI: # lsusb -v | grep " i" Invalid product/subclass spec at line 2650 idVendor 0x0000 idProduct 0x0000 iManufacturer 0 iProduct 2 USB UHCI Root Hub iSerial 1 1860 iConfiguration 0 iInterface 0 and the PCMCIA appears as two OHCI hubs on a PCI hub... # lsusb -v | grep " i" Invalid product/subclass spec at line 2650 idVendor 0x0000 idProduct 0x0000 iManufacturer 3 Linux 2.4.21-0.13mdk ehci-hcd iProduct 2 PCI device 1033:00e0 iSerial 1 02:00.2 iConfiguration 0 iInterface 0 idVendor 0x0000 idProduct 0x0000 iManufacturer 0 iProduct 2 USB OHCI Root Hub iSerial 1 e08b1000 iConfiguration 0 iInterface 0 idVendor 0x0000 idProduct 0x0000 iManufacturer 0 iProduct 2 USB OHCI Root Hub iSerial 1 e086c000 iConfiguration 0 iInterface 0 ### builtin... idVendor 0x0000 idProduct 0x0000 iManufacturer 0 iProduct 2 USB UHCI Root Hub iSerial 1 1860 iConfiguration 0 iInterface 0 Here is the full dump... [Actually, the original msg with full dump fails to end with a FIN, so I've truncated it to give the gist of the problem for now...]
