Ok I wrote my own custom matcher using the bus no and device file name to distinguish between two usb devices. It worked fine in a test application I wrote. But when I tried to use the same technique in the application I was supposed to use it in , I ran into some bugs..
In my application I read the usb busses every 100 ms or so and then I compare the handles I got on the second read with the previous read and if the number of devices I get is different , I update my application to recgnosize the new device. If there is a change then I delete the old handles I got and use the new handles to update my program or else I use my old handle itself and delete the new handles. Sometimes when I have only one hub connected the no of usb devices read is not stable and keeps varying between 0 and 1. I know its hard say anything just by this explanation but any pointers as to what the problem may be will be helpful. :) Thanks Shivaprasad On Thu, Jun 26, 2008 at 5:41 PM, Charles Lepple <[EMAIL PROTECTED]> wrote: > On Jun 26, 2008, at 12:56 AM, shivaprasad javali wrote: > > > Will I have to write my own custom matcher function? > > > Most likely, yes. > > -- > Charles Lepple > > > _______________________________________________ > libhid-discuss mailing list > [email protected] > http://lists.alioth.debian.org/mailman/listinfo/libhid-discuss > _______________________________________________ libhid-discuss mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/libhid-discuss
