Hi, Yes you are right, it is a Arcom Viper.
The 2.6 Kernel code might be interesting, especially as there are numerous posts on here regarding people willing to try and port the isp116x code to 2.6.x. I'm not aware how much the usb code has changed between 2.4.x -> 2.6.x but I am guessing it cannot be too extensive changes required, nor should it be difficult to work by comparing diffs of already ported drivers. >> Also, if you have any queries about the USB hardware etc on the VIPER please don't hesitate to ask. What is the interrupt trigger source for the isp116x on the Viper? (i.e. is it set up to be edge or level triggered) Could you also tell me which webcams you have tried with it? The pwc driver with phillips/logitech seems to be the most common (and is what I'm attempting to get working) but it would be interesting to see if any others have been tried. Also do you have any comment on this: // this chip (isp116x) gives a pulse of 167ns on the interrupt, pxa250 requires 1000ns As I cannot find this requirement documented anywhere in the publicly available docs I was wondering if you had any better information?

You are presumably referring to our VIPER board. I am (of course) also interested in having an ISP116x driver which works well on the PXA processor. The existing driver in our kernel (I used the tango one) works well enough for storage & hid devices but not at all for webcams/ISO transfers. If you would like I can offer you a pre-release of the 2.6 kernel support for the VIPER. The majority of the peripherals are supported, apart from USB (of course) and COM4/COM5 which don't work for some unknown reason. 2.6 might be a better base for this sort of work. Also, if you have any queries about the USB hardware etc on the VIPER please don't hesitate to ask.
