ACR122U libusb error

[audunmg]

Trying to use ACR122U with pcscd and it throws these errors 31905 times:

It repeats and fills the logs pretty fast.

Using acsccid compiled from latest master on arch linux.

According to the log, it is very strange that two ACR122U readers have same USB serial number "A02014090501". I remembered that ACR122U reader does not store this property.

Do you know the firmware version?

[audunmg]

Sorry, I don't know how do i find the firmware version. Do you know if it's possible to update it?

I only have one reader, but it shows up as two readers when it shows up:

$ pcsc_scan 
Using reader plug'n play mechanism
Scanning present readers...
0: ACS ACR122U (A02014090501) 00 00
1: ACS ACR122U (A02014090501) 00 01

The ACR122U reader has only 1 slot and it seems that your reader is not a genuine ACR122U reader. According to the log, the reader does not accept any command and I think that you cannot send the command to get the firmware version.

Can you paste the output of the command sudo lsusb -v?

[audunmg]

Here's the output of lsusb -v:

Comparing the value with the original ACR122U reader, I believe that your reader is fake. Please contact your retailer for refund.

Thank you for your time, it turned out to be fake.
