| Summary | 0000385: ACS ACR122U init failed: device or resource busy | ||||
| Description | $ tail -f /var/log/syslog Jun 14 10:17:48 raspberrypi pcscd: ccid_usb.c:575:OpenUSBByName() Can't claim interface 001/008: Device or resource busy Jun 14 10:17:49 raspberrypi pcscd: ifdhandler.c:118:IFDHCreateChannelByName() failed Jun 14 10:17:49 raspberrypi pcscd: readerfactory.c:972:RFInitializeReader() Open Port 0x200000 Failed (usb:072f/2200:libudev:0:/dev/bus/usb/001/008) Jun 14 10:17:49 raspberrypi pcscd: readerfactory.c:279:RFAddReader() ACS ACR122U init failed. $ uname -a Linux raspberrypi 3.12.22+ 0000691 PREEMPT Wed Jun 18 18:29:58 BST 2014 armv6l GNU/Linux Older Raspberry Pi worked fine: Linux pi-demo 3.6.11+ 0000538 PREEMPT Fri Aug 30 20:42:08 BST 2013 armv6l GNU/Linux SOLUTION: https://wiki.archlinux.org/index.php/Touchatag_RFID_Reader : "When the ACR122U plug in, kernel(>3.5) will automatic load the pn533 driver. With the pn533 driver, pcscd will report "Can't claim interface" error. Use below command to disable pn533 and nfc driver in kernel." ... $ sudo vi /etc/modprobe.d/blacklist.conf # ... and make sure that the file contains the following 2 lines: install nfc /bin/false install pn533 /bin/false Also see: http://www.libnfc.org/community/topic/1241/raspberry-pi-acr122-unable-to-claim-usb-interface-device-busy/ (also pointing at blacklisting pn533 and nfc drivers, did not try this solution though, since the above one works fine) | ||||
