Hello,
I am trying to get a philips pcvc680k camera to work with my dell CPx laptop.
The problem I have is that I get heaps of errors when I insert the device:
-----------------
usb_control/bulk_msg: timeout
usbdevfs: USBDEVFS_CONTROL failed dev 3 rqt 128 rq 6 len 486 ret -110
usb_control/bulk_msg: timeout
usbdevfs: USBDEVFS_CONTROL failed dev 3 rqt 128 rq 6 len 486 ret -110
usb_control/bulk_msg: timeout
usbdevfs: USBDEVFS_CONTROL failed dev 3 rqt 128 rq 6 len 486 ret -110
usb_control/bulk_msg: timeout
usbdevfs: USBDEVFS_CONTROL failed dev 3 rqt 128 rq 6 len 486 ret -110
-----------------
and so on for a few hundred messages.
(/var/log/messages reports usb_control/bulk_msg: timeout is repeated 159 times)
This is without loading the driver.
I get these errors both with 2.4.2 and 2.4.3. I have tried both uhci drivers.
When I load the driver and try to access the device I get more
error messages.
-----------------
pwc Philips PCA645/646 + PCVC675/680/690 + PCVC730/740 webcam module version 6.2 PPro

usb_control/bulk_msg: timeout
usb_control/bulk_msg: timeout

usb_control/bulk_msg: timeout
-----------------
And so on. This was with 2.4.2 (I don't think 2.4.3 is supported yet)
(reading the webpage a bit more - perhaps it is because I was testing
with xawtv?)
I can get the microphone part to appear to work.
