libusb_set_configuration error -6

I'm trying to read/write a chinese "203-ID-RW" device. The lsusb -v output is the same of what reported in the idrw_linux.c file.

This is the dmesg output:

[  602.657079] usb 1-1.3: new full-speed USB device number 8 using dwc_otg
[  602.844249] usb 1-1.3: New USB device found, idVendor=6688, idProduct=6850
[  602.844265] usb 1-1.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3

Here the output of your program:

# ./idrw_linux -v -r
Successfully found the RFID R/W device
libusb_set_configuration error -6

and here some further output in dmesg;

[ 608.765459] usb 1-1.3: usbfs: interface 0 claimed by usbhid while 'idrw_linux' sets config #1

Even issuying lsusb -v does nothing. I tried also as a root.
Is there something I could try to do?

UPDATE:
Just to be sure, I tried to exclude usbhid using this rule:

SUBSYSTEMS=="usb", DRIVERS=="usbhid", ACTION=="add", ATTR{authorized}="0"

now the error is different:

Successfully found the RFID R/W device
libusb_claim_interface error -4

I have no direct idea what to do. Maybe unload the usbhid module before.

Try to check if the following udev rules has been installed:

ATTR{idVendor}=="6688", ATTR{idProduct}=="6850", MODE="664", GROUP="plugdev"

And your user must be in plugdev group

I've the same issue about :

./idrw_linux -v -r
Successfully found the RFID R/W device
libusb_set_configuration error -6

Even if I copy the 20-rwrfid.rules in /dev/udev/rules.d and restart it...
( "lsusb" is showing the device properly ... )

The "dmesg" related output is :

EDIT : The previous tests are done on my Ubuntu 14.04 desktop, but this morning, I did the same tests on an OrangePiPCPlus with Armbian Stetch Linux 5.1.0-rc7, and the results were exactly the same ...

Same here. Dmesg:

[dinux@dinux rfid_app]$ sudo ./rfid_app -l

Related with #14 but tried three different USB ports

Tried this #3 (comment)
Result:

[dinux@dinux rfid_app]$ sudo ./rfid_app -d /dev/bus/usb/003/012 -l
Unknown or no device found:�fPh	)

idrw_linux command returns:

[dinux@dinux rfid_app]$ sudo ./idrw_linux -r
libusb_claim_interface error -4

Windows application works as expected. Link http://download.5yoa.com/IDW02.zip

Hi,

I'm having exactly the same issue, using Kali linux. Does anyone know how to disable the lock that hid puts on the device?

[merbanan]

Try commenting out the libusb_claim_interface call in the code.

[OrYaYo]

Hi,

When I uncomment the libusb_claim_interface call (the whole section), I get the same error:

./idrw_linux -v -r
Successfully found the RFID R/W device
libusb_set_configuration error -6

If I do what has been mentioned by Mark-81, which is the following:

SUBSYSTEM=="usb", DRIVERS=="usbhid", ACTION=="add", ATTR{authorized}="0"

without removing the libusb_claim_interface call, I would get the error:

Successfully found the RFID R/W device
libusb_claim_interface error -4

This is expected.

When removing the libusb_claim_interface call, I get the follwing error:

# ./idrw_linux -v -r
Successfully found the RFID R/W device
CMD_GET_SNR
CRC_OK = 0x26
Outgoing packet, pkt_pl_unk = 0x08
STX OK 0xaa
ETX OK 0xbb
CMD_GET_SNR: 0x00 0x00

Control Out error -4

I have to say that the compiled binary now waits for the USB device to read the tag, but one the tag is read, it displays the error shown.

Any ideas?
