Title: Issue with GekkoScience 8 Port Base Hub Post by: poonasor on January 01, 2023, 10:19:23 PM Original topic: https://bitcointalk.org/index.php?topic=5431064.0
I purchased 2 GekkoScience USB Hubs from 419Mining back in April 2022 the first one I opened and used - nothing was wrong with it, the 2nd one I opened back in October, and one by one the powered USB ports started to not get any power I've attached a USB reader to each port for testing and this was using a FutureBit ApolloBTC 200W Power Supply https://imgur.com/a/Z0X2okL And just today, all of the 6A ports are getting no power the only 2 that works is the 2 fan ports My next step is to try to get the barrel-type power supply and continue to test, hopefully, it'll fix the problem. Not sure if anyone else has experienced this with the GekkoScience USB Hub, really hope I can fix this hub Now I'm noticing that the 2 Compac Fs I had on this hub are showing 0 chips found thx in advance Title: Re: Issue with GekkoScience 8 Port Base Hub Post by: Sledge0001 on January 02, 2023, 01:01:50 AM I've burned up quite a few of these by pushing the sticks over 580MHz. The old hubs seem to die in sections of 2.
The newer ones have a "reset" when you leave the port unoccupied for a bit of time. The old ones don't seem to have anything that I've found to bring them back to life. I'd be interested if you find a fix as I've got several in a similar state. Title: Re: Issue with GekkoScience 8 Port Base Hub Post by: NotFuzzyWarm on January 02, 2023, 02:44:53 AM There are 3x high current regulators, 1 for each pair pf ports. Each regulator is spec'd at 6A max to be divided between each of the 2 ports. The fix is to replace the blown regulators and drop your settings to pull less current than what they can supply.
The new ones use PTC-fuses to limit max current to each port to 3.5A(?) and yes once tripped they reset in a few min once they cool down.

I'm interested in sending several in if you can! (assuming their US based). |
