nfc-list fails with PN533 usb device #221

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Build and install libnfc-1.7.0-rc2 from source
2. Insert NXP PN533 usb NFC reader
3. run sudo nfc-list

What is the expected output? What do you see instead?

I expect a list of nearby nfc tags. Instead I get:

nfc-list uses libnfc libnfc-1.7.0-rc2
error   libnfc.driver.pn53x_usb Unable to set USB configuration (Device or 
resource busy)
No NFC device found.

What version of the product are you using? On what operating system?

libnfc-1.7.0-rc2 on Arch Linux x86_64 with kernel 3.6.11

Please provide any additional information below.

dmesg:

[ 3029.399082] pn533 4-2:1.0: NFC: NXP PN533 firmware ver 2.7 now attached
[ 3034.547509] usb 4-2: usbfs: interface 0 claimed by pn533 while 'nfc-list' 
sets config #1

Well the dmesg is clear enough:
pn533 kernel driver is loaded and should be removed:
modprobe -r pn533
