Problem with connect more than one usb device

[aaronsuns]

Hi,

I have a problem with connect with more than one usb device, could you help?

$ lsusb |grep ST-LINK
Bus 002 Device 111: ID 0483:3748 SGS Thomson Microelectronics ST-LINK/V2
Bus 002 Device 112: ID 0483:3748 SGS Thomson Microelectronics ST-LINK/V2
$ ls -l /dev/ |grep usb
lrwxrwxrwx 1 root root 15 Oct 2 16:05 stlinkv2_1 -> bus/usb/002/111
lrwxrwxrwx 1 root root 15 Oct 2 16:07 stlinkv2_2 -> bus/usb/002/112
crw------- 1 root root 252, 0 Oct 1 16:36 usbmon0
crw------- 1 root root 252, 1 Oct 1 16:36 usbmon1
crw------- 1 root root 252, 2 Oct 1 16:36 usbmon2

Then I try to start st-utils:

$./st-util -d /dev/stlinkv2_1

They just try to connect the same device, it seems the device option doesn't work.
