Well, all the information in the device and current config descriptors is already available in sysfs, just spread out among several files. The interface and endpoint descriptor information is also available in the appropriate subdirectories (although only the info for the currently-installed configuration is in sysfs). I shouldn't think it would be too much harder to read several sysfs files than a single usbfs file. Do you really need anything other than the vendor ID, the product ID, and perhaps the bcdDevice value?
