Hello, again!
Well, with lots of debugging enabled, I got to some more details about the non working DMC TSC-10 USB Touchscreen:
(see also: http://lkml.org/lkml/2007/6/26/228 )
Whenever I plug in the TSC-10 I get the following output
hub 3-0:1.0: state 7 ports 4 chg 0000 evt 0004 ehci_hcd 0000:00:14.2: GetStatus port 2 status 001403 POWER sig=k CSC CONNECT hub 3-0:1.0: port 2, status 0501, change 0001, 480 Mb/s hub 3-0:1.0: debounce: port 2: total 100ms stable 100ms status 0x501 ehci_hcd 0000:00:14.2: port 2 low speed --> companion ehci_hcd 0000:00:14.2: GetStatus port 2 status 003402 POWER OWNER sig=k CSC hub 3-0:1.0: state 7 ports 4 chg 0000 evt 0004 hub 2-0:1.0: state 7 ports 2 chg 0000 evt 0002 ohci_hcd 0000:00:14.1: GetStatus roothub.portstatus [0] = 0x00010301 CSC LSDA PPS CCS hub 2-0:1.0: port 1, status 0301, change 0001, 1.5 Mb/s hub 2-0:1.0: debounce: port 1: total 100ms stable 100ms status 0x301 ohci_hcd 0000:00:14.1: GetStatus roothub.portstatus [0] = 0x00100303 PRSC LSDA PPS PES CCS usb 2-1: new low speed USB device using ohci_hcd and address 16 ohci_hcd 0000:00:14.1: GetStatus roothub.portstatus [0] = 0x00100303 PRSC LSDA PPS PES CCS usb 2-1: default language 0x0054 usb 2-1: wrong descriptor type 00 for string 1 ("TSC-10 DM") usb 2-1: new device strings: Mfr=1, Product=0, SerialNumber=0 usb 2-1: Manufacturer: TSC-10 DM usb 2-1: uevent usb 2-1: usb_probe_device usb 2-1: configuration #1 chosen from 1 choice usb 2-1: adding 2-1:1.0 (config #1, interface 0) usb 2-1:1.0: uevent usbtouchscreen 2-1:1.0: usb_probe_interface usbtouchscreen 2-1:1.0: usb_probe_interface - got id drivers/usb/input/usbtouchscreen.c: usbtouch_probe - type->init() failed, err: -19 drivers/usb/core/inode.c: creating file '016' hub 2-0:1.0: state 7 ports 2 chg 0000 evt 0002
And when I unplug it, it cleans up the device properly:
hub 2-0:1.0: state 7 ports 2 chg 0000 evt 0002 ohci_hcd 0000:00:14.1: GetStatus roothub.portstatus [0] = 0x00010100 CSC PPS hub 2-0:1.0: port 1, status 0100, change 0001, 12 Mb/s usb 2-1: USB disconnect, address 16 usb 2-1: unregistering device usb 2-1: usb_disable_device nuking all URBs usb 2-1: unregistering interface 2-1:1.0 usbdev2.16_ep81: ep_device_release called for usbdev2.16_ep81 usb 2-1:1.0: uevent usbdev2.16_ep00: ep_device_release called for usbdev2.16_ep00 usb 2-1: uevent hub 2-0:1.0: debounce: port 1: total 100ms stable 100ms status 0x100
Any ideas of what's wrong here before I have to start to dig deeper in the source?!
The touchscreen controller chip is a TSC-103 088 F3J0 it has no EEPROM attached. (which should be optional to save calibration data) The USB controller is a Philips ISP1563BM PCI Host Controller DateCode April-2006.
The same problem appears with 2.6.21.5 and 2.6.20.1-ubuntu-something on x86 platform.
