New devices have the same ID and are indistinguishable #40

Hello, devices I've bought recently (2 relay version) all have the same ID=HURTM:

hidusb-relay-cmd.exe ENUM
Board ID=[HURTM] State: R1=OFF R2=OFF
Board ID=[HURTM] State: R1=OFF R2=OFF

It is impossible to address them independently, only the first one reacts. This makes them useless.

Is there any workaround to this? I'm using Windows 10.

See this closed issue https://github.com/pavel-a/usb-relay-hid/issues/24. If you can use Linux, you should also look at this code https://github.com/darrylb123/usbrelay with details here: https://github.com/darrylb123/usbrelay/issues/18. You'll be able to change their IDs - e.g. ./usbrelay HURTM_0=NEWID (with new ID NEWID). This change is written somewhere directly to the relay board and on Windows, you see it with your new ID. I don't know if it could be compiled also under Win.
