I have an RCA VR5320 digital voice recorder. It has a usb connector,
but isn't recognized by SL 5.6. I get log messages of the form
kernel: usb 1-5: new high speed USB device using ehci_hcd and address 4
kernel: usb 1-5: ep0 maxpacket = 32
This is evidently a known problem and there is a patch for
drivers/usb/core/hub.c with the comment "A few devices (such as the RCA
VR5220 voice recorder) are so non-compliant with the USB spec that they
have invalid maxpacket sizes for endpoint 0. Nevertheless, as long as
we can safely use them, we may as well do so." I think this patch is
incorporated in 2.6.32 kernels.
Q1: Am I correct in thinking that I would have to compile a whole new
kernel, as opposed to just a module, to incorporate a patch to hub.c?
Q2: Is there any sort of module or userspace hack I could try instead?
I don't want to get into a position of maintaining my own kernel. I'd
rather wait until I catch up with 2.6.32 and impose on friends with
newer kernels or windows machines in the meantime.
Thanks.
