Date: Sat, 7 Apr 2007 02:54:58 +0200 From: Helge Hafting <helgehaf@...el.hist.no> To: linux-kernel@...r.kernel.org Cc: linux-usb-devel@...ts.sourceforge.net Subject: usb touchscreen breakage in 2.6.21-rc5-mm4 ? 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?
