Hi there guys, I recently bought 02 webcams (me and my sister) with this chip microdia 0c45:6242> Below is the output form my lsusb: Bus 002 Device 003: ID 0c45:6242 Microdia Bus 002 Device 002: ID 04b4:6560 Cypress Semiconductor Corp. CY7C65640 USB-2.0 "TetraHub" Bus 002 Device 001: ID 0000:0000 Bus 001 Device 001: ID 0000:0000So, I tried the gspca module but didn't work. Then yesterday I went to git clone git microdia and installed the microdia driver It kept saying "could not find /dev/hda0" on camorama. Mplayer also couldn't open the device. Xawtv also didn't work. Now I have downloaded the latest sn9c20x and the dmsg output is as follows: sn9c102: V4L2 driver for SN9C1xx PC Camera Controllers v1:1.47 usbcore: registered new interface driver sn9c102 usbcore: deregistering interface driver sn9c102 sn9c20x: SN9C20X USB 2.0 webcam driver loaded sn9c20x: SN9C20X USB 2.0 Webcam - 0C45:6242 plugged-in. sn9c20x: Write register failed index = 0x1000 sn9c20x: Bridge Init Error (-71). line 0 sn9c20x: Device Init failed (-71)! usb_sn9c20x_driver: probe of 2-2:1.0 failed with error -71 usbcore: registered new interface driver usb_sn9c20x_driver sn9c20x: v2008.11 : SN9C20X USB 2.0 Webcam Driver microdia: Microdia USB 2.0 webcam driver loaded microdia: Microdia USB 2.0 Webcam - 0C45:6242 plugged-in. microdia: Detected SN9C20X Bridge microdia: Write register failed index = 0x1000 microdia: Bridge Init Error (-71). line 0 microdia: Device Init failed (-71)! usb_microdia_driver: probe of 2-2:1.0 failed with error -71 So I unloaded the driver sn9c20x microdia: usb_microdia_exit: Microdia USB 2.0 webcam driver unloaded usbcore: deregistering interface driver usb_microdia_driver And the loaded it again sn9c20x: sn9c20x: SN9C20X USB 2.0 webcam driver loaded sn9c20x: SN9C20X USB 2.0 Webcam - 0C45:6242 plugged-in. sn9c20x: Write register failed index = 0x1000 sn9c20x: Bridge Init Error (-71). line 0 #error detecting the bridge sn9c20x: Device Init failed (-71)! usb_sn9c20x_driver: probe of 2-2:1.0 failed with error -71 usbcore: registered new interface driver usb_sn9c20x_driver sn9c20x: v2008.11 : SN9C20X USB 2.0 Webcam Driver Then I unload it and load the first microdia driver, wich compialed to microdia.ko and the DMESG output is as follows: microdia: Microdia USB 2.0 webcam driver loaded microdia: Microdia USB 2.0 Webcam - 0C45:6242 plugged-in. microdia: Detected SN9C20X Bridge microdia: Write register failed index = 0x1000 microdia: Bridge Init Error (-71). line 0 microdia: Device Init failed (-71)! usb_microdia_driver: probe of 2-2:1.0 failed with error -71 usbcore: registered new interface driver usb_microdia_driver microdia: v2008.11 : Microdia USB 2.0 Webcam Driver It seems that, the previous driver (microdia) fails on detecting the sensor and the sn9c20x driver fails on detecting the bridge and the sensor... Am I right? Guys, I do need some help...
And I'll try my best here: There is no problem detecting sensor or bridge.The error -71 has it's origin within the usb subsystem and our driver simply passes it on. -71 (very helpfully) means "protocol error".
Of course the susbsystem is silent about the actual cause which may be a delayed impulse, a broken cable or a problem in your camera. No way of knowing.
To test your webcam I advice to test it with another computer (and maybe a live cd capable of compiling kernels).
Apart from that:Keep trying. Maybe it will work on a sunny day with a lot of solar flares (who knows ;) ).
Good luck. GWater
