Dear Users, On ebay I got a usb remote control. This is a ir receiver having a usb plug and an ir remote control sender. It is a Cypress Semiconductor eDio USB Multi Remote Controller from Formosa Industrial Computing, Inc. lsusb shows Bus 003 Device 023: ID 147a:e006 Formosa Industrial Computing, Inc. However I want to receive the key strokes I tried cat /dev/input/event3 | xxd But just the first press after plugging in is received. To receive more events you have to plug in again. the same applies to evexec, but the data displayed is incorrect Looking at usbmon output looks like this ( when something is requesting data from the receiver) dee5f2e0 614940404 C Ii:023:01 0 4 = 40001b0f dee5f2e0 614940421 S Ii:023:01 -115 4 < dee5f2e0 615036386 C Ii:023:01 0 4 = 40801b0f dee5f2e0 615036401 S Ii:023:01 -115 4 < dee5f2e0 615284335 C Ii:023:01 0 4 = 40801b0f dee5f2e0 615284353 S Ii:023:01 -115 4 < This looks better. Every keystroke is received. But i realized thet the data sent is different. For every event there are 4 bytes sent (but my usb keyboard always sends 8 bytes) I suspect an incompatibility with the usbhid driver which requests 8 bytes but just gets 4 bytes each time and so just works out for the 1st event. I really accept writing my own usb driver(i already have experiance) but my driver is never used for my remote device, as usbhid still takes precedence and i cannot remove the usbhid driver, because its not compiled as a module. How can I best properly receive the remote keystrokes without having to parse the usbmon output ? rds -- "Feel free" - 5 GB Mailbox, 50 FreeSMS/Monat ...
