I recently had major difficulties installing a new USB Keyboard and finding all the files for it. Not only did I need the famous "hidusb.sys", but I also ended up needing "hidparse.sys", "hidvkd.sys", "hidclass.sys", "hiddev.inf" and since I was installing a keyboard I also needed "kbdhid.vxd". So I've compressed each of these files onto one zip file for others. Use them as needed. Please provide feedback as I'd like to know if this works or if I could add some files to this download.
Thank you and good luck.
