Pendant XHC-WHB04B-4 - Constant USB disconnects

PIcked up a  XHC-WHB04B-4, which is the 4-axis MPG variant. I've seen a lot of discussion about the XHC-WHB04B-6, the 6 axis version.

My issue, before worrying even about udev or HAL or anything... constant USB disconnects.

1. Plug in USB receiver
2. I can see it pop up
3. Let it idle a bit. As soon as I interact with the MPG, the USB device disconnects.
4. In another few seconds, the device will reconnect.
5. Rinse and repeat over and over.

I've tried it on 2 PC's (one was windows), and this is on the USB port directly on the back of the motherboard. My initial thought it faulty hardware obviously, possibly drawing more then 500mA, could be blowing the soft-fuse and cycling over and over.

Before opening a dispute with the vendor, just want to check if anyone else came across this.

It's not something that I have heard of here on the forum (I have no first-hand knowledge of these pendants)

I have bought WHB04B-4 also from China and having same issue
Tried all, from BIOS setup configuration, different udev rules but can't get it working
Also contacted seller on AliExpress so will see if can help in this situation

If you have sorted it in mean time please let me know

Thanks

So to give an update regarding this
I have bought new USB receiver (30$) and didn't work out of box so seller from AliExpress provided me with pairing SW
Managed to get new one to work BUT also tried on OLD one and now it works also
So don't buy new one use this SW and try (use Google translate for steps) maybe will create translated doc later)
Let me know if it works for you

P.S.
I have done this from VirtualBox with WIndows 10 (not responsible for anything using this SW)  

I am also having this same issue with one of these pendants. I re-paired it as suggested in this thread but the same behavior is happening. On the windows machine that I pair it on it seems to work fine, but when plugged into my LinuxCNC machine the USB disconnects every few seconds (ie device disappears from lsusb), then reconnects after a few seconds. The display on the pendant is unchanged.

I have not set it up in LinuxCNC due to this issue. Is this correct behavior if the pendant does not receive any traffic from the PC for a while?

I have tried few times until worked for me as I have 2 so was doing multiple retries (not sure if that is the case but worth trying)

Also few notes check udev rules and that is NOT on USB hub, for me that worked fine after since then and I have no problems or issues

Let me know if worked
