Never mind, I have fixed this issue. I have uninstalled libusb drivers, 
unticked acr122u USB in cmake and using the old PC/SC driver, which works 
great. 

But I have not managed to make libnfc work with libusb with my reader

Same issue on XP 32-bit

libusb0-sys:err [claim_interface] device is not configured

According to 
http://sourceforge.net/apps/trac/libusb-win32/wiki/libusbwin32_documentation

usb_set_configuration must be called with a valid configuration (not 0) before 
you can claim the interface.

Actually, usb_set_configuration is not required. The problem is usb_reset.

After calling usb_reset, the device will need to re-enumerate and thus requires 
you to find the new device and open a new handle. The handle used to call 
usb_reset() will no longer work.

Comment the line of usb_reset(data.pudh) in acr122_usb_open

I have same issue and tried suggestion that I found here  
http://www.libnfc.org/community/topic/791/solved-why-nfclist-only-works-with-sud
o-using-pn53x-usb-device/

with no success.

When I run nfc-list under the root user - everything is fine but when I try to 
do it under the regular user I get:

error   libnfc.driver.acr122_usb    Unable to claim USB interface (Operation not 
permitted)
nfc-list: ERROR: Unable to open NFC device: acr122_usb:004:002

I can reproduce this only on 32-bit Ubuntu: 12.04.3 LTS.
On 64-bit Ubuntu (of same release version) everyting is fine and I can work 
with the reader under the regular user.

Can you check the rights of the device?

 lsusb -> where is it? ->
 ls -l /dev/bus/usb/xxx/xxx
Has the group "rw-" access? Are you member of that group?
Are there extended ACLs?
 getfacl /dev/bus/usb/xxx/xxx

Is there any other program using the device? Check with
 sudo lsof -n |grep /dev/bus/usb/xxx/xxx
Is pcscd running? Try stopping it.

I think maximchick's problem is not related to this issue.

maximchick: maybe udev rules have not been installed in your system, so you 
will probably have permissions issue.
