Now that usbhid-dump is integrated into usbutils git, just wondering if it makes sense to integrate hidrd (which provides hidrd-convert) as well. If not, usbhid-dump is not that useful after all.
I don't think it is entirely a good idea. After all, hidrd-convert is mainly a development/hacking tool and could theoretically be used on a system unsupported by libusb and/or not having USB at all. Then, its unique feature is the ability to edit existing binary descriptors, which requires libxml2 currently. It wouldn't be very nice either to have usbutils depend on it, or to ship hidrd without editing support.
From the site, typical use of usbhid-dump will be redirect the output to hidrd-convert to dump human readable format. http://digimend.sourceforge.net/#proj-hid-dump
Another important feature (and I guess most important for some) is the report dumping, which doesn't require hidrd-convert at all.
One more thing, right now I need to use lsusb to find the bus and device number first before I can run usbhid-dump, is it possible to add the "-d vid:pid" option just like lsusb?
Yeah, I think it would be nice to have, although would require adjusting existing interface a bit.
BTW, it is working nicely. For example, if I need to dump the HID report descriptor of a USB composite device (interface 1), then I need to manually unbind the kernel driver in order to use "lsusb -vvv". But usbhid-dump makes things easier.
Glad to hear that :) I think lsusb could benefit from an option enabling detachment/attachment of the listed devices.
