I have a USB desktop reader "ACR1281U" which is a basic keyboard emulation reader. When you "swipe" the card it'll output it's ID and run a ENTER-command.
When I plug this into my Raspberry Pi it'll work from time to time with 1-2 swipes and sometimes it doesn't work at all. This is with all default drivers - I haven't installed anything else then just input the USB-device into my R-Pi.
First I thought that the official driver from ACS could/would solve this so I went to their website http://www.acs.com.hk/en/driver/36/acr128u-dual-interface-smart-card-reader/ but found out that they only have their driver (.deb) package as i386 and amd64.
Do I really need to official driver or can I somehow troubleshoot my device as it is now? When I boot up I can see that the RPi detects the correct USB device on input. Is there something I can do to troubleshoot this further?
