Hi,

as you have seen I've some LA devices running on several frequencies. The other half of my devices is running on standard frequencies, controlled by the standard controller. When I came home today I realized, that 5 devices stopped working. They are not blinking any more. I plugged out, in again and again.

Nothing happens to them any more.

I had the same issue on one device approx 30 minutes after start up of the system. It had something burned next to the usb connector on the board. I'm now missing a total of 6 devices out of 20 :-/ Jack promised to send me one on replacement two weeks ago. Now I'm at six and don't have the first one yet. Any one knows how to claim the warranty with Jack?? *damn it* ROI is running away.

Any one else facing those problems??? Any one able to repair that???

Are all 5 coming off the same PSU or 1/2 of a USB Hub? I had a similar problem where 5 of my miners died (still had the flashing lights but no hashing). Flashing lights powered by USB. Fans/hashing powered by PSU. I traced it down to a bad PSU which Jack replaced no charge. I was also able to order a 30A 12V psu (for LED lighting) from EBay for £16 (looks exactly like the L.A. PSU) so I now have a backup PSU.

yes, they are all coming off from 1/2 of a USB hub. I still use the same PSU... the remaining devices work just fine - also on the burned ones the fans are rotating like always... seems like just USB connection is gone. I tried to exchange the usb ports on the hub. Finally the units themselves seem to be the problem here. Jack now asked me to send them back for repair which is of course very nice from him but I'm scared it will take weeks to get them back working.

If it helps it took 13 days from the time I told Jack about the blown PSU to receiving the replacement. Told him on the 12th of March and had the PSU in my hands on the 25th. You might want to check out that USB hub though and make sure the 1/2 that has the blown miners on it still works.
