I have an usb touchscreen (egalax variety) that works with the 2.6.18 kernel supplied by debian.
It fails when I compile 2.6.21-rc5-mm4, tuned to the machine in question. Unlike the debian kernel, this kernel don't use modules in order to save boot time. The strange thing is, 2.6.21-rc5-mm4 recognizes the device. dmesg says things like usb 3-2: Manufacturer: eGalac Inc. usb 3-2: Product: USB TouchController and a lot more. Unlike 2.6.18, it never gets around to say "usbcore: registered new driver usbtouchscreen" which seems to indicate a problem. usbcore registers several other drivers, such as usbserial and pl2303 that makes the gps work. It also registers other drivers like usb-storage,usbfs,hub,libusual,hiddev,usbhid. But not usbtouchscreen. I believe I have turned on every config option for usb touchscreen, this should not be missing. Is there something wrong, or could there be a seemingly unrelated option that I need to turn on?
