Hi all,
I'm looking for a USB sniffer for linux; but i found in google only sniffer USB for Windows (as usbsnoopy).
Some of those are more like "API tracers" than an on-the-wire Sniffer. (Which I rcall as a TM for on-the-wire Ethernet Sniffers.)
That is, like CATC (for USB) with Linux based analysis/display tools...
Does anybody know any USB sniffer sofware working under linux?
A USB sniffer under Linux doesn't make much sense.
Think about why you need a sniffer...
Under some circumstances it can make sense. Suppose you want to test a host controller driver implementation? Or suppose you want to see what packets a driver is sending/receiving without going to the time and trouble of adding all sorts of debugging code? -- especially if someone else wrote the driver and you don't understand it very well.
Yes, and I think there are two spots in "hcd.c" identifying the right place to have an API sniffer call out to some event logging code (for submit and giveback). This would be trivial to add to USB, if you've got some kind of logging and analysis toolset to hook it up to ... :)
