How to play back USB traffic?
kelkka opened this issue · comments
Hello,
Maybe I don't follow exactly what this software does, but I'm looking to record USB-traffic on Windows and be able to playback that exact traffic later.
So, I record traffic using wireshark and usbpcap, and I try moving the mouse which is device 3.9.1 and expect that the mouse movement will replay if I run the script output by usbrply later.
I open the pcapng with usbrply with:
usbrply --device-hi -p mousecap.pcapng
which prints:
# Generated by usbrply
# cmd: usbrply --device-hi -p mousecap.pcapng
def replay(dev):
def bulkRead(endpoint, length, timeout=None):
return dev.bulkRead(endpoint, length, timeout=(1000 if timeout is None else timeout))
def bulkWrite(endpoint, data, timeout=None):
dev.bulkWrite(endpoint, data, timeout=(1000 if timeout is None else timeout))
def controlRead(request_type, request, value, index, length,
timeout=None):
return dev.controlRead(request_type, request, value, index, length,
timeout=(1000 if timeout is None else timeout))
def controlWrite(request_type, request, value, index, data,
timeout=None):
dev.controlWrite(request_type, request, value, index, data,
timeout=(1000 if timeout is None else timeout))
# Generated by usbrply
# Source: Windows pcap (USBPcap)
# cmd: usbrply --device-hi -p mousecap.pcapng
# Selected device 14
I tried using --device 9 to maybe make it use the mouse? But it says it selected device 14 anyway and nothing changes. I managed to get Selected device 9 at some point but it doesnt seem to matter (should really be 3.9.1 anyway? But dots are not allowed when specifying device). The capture file has a bunch of data but the script has nothing except the default text as I understand it.
Not sure what's going on or what I should expect from this software. Are there only specific devices that are supported? How do I know if my USB-device is supported in that case?
Thanks
Hi! I'm guessing this is HID traffic which is interrupts / isochronous. Generally usbrply doesn't support that terribly well. However if you send you capture over I can look into adding better support.
Please let me know if there is anything I can do, otherwise I will assume this is solved and close ticket for inactivity. Thank you.
Sorry, I had to put this on hold for a while, and I no longer have the recording, but you can record this easily yourself by just using any USB mouse I guess, yes it was HID.
I think I'll have to use some other software for my purpose anyway, the mouse was just a test to see how/if this one works.
