I recently acquired a Block Erupter 49 port USB 2.0 Hub Rev 2.00 (Red board) to use with my 2PAC and Terminus pod that I purchased from sidehack as well as some miscellaneous USB miners. Finding information about these hubs are more elusive than I imagined. Does anyone know of a support thread or other resource to post my questions to?
1) Who was the OEM/Primary distributor for these back in the day? Asicminer? Eyeboot? Someone else?
2) The unit has what appears to be a 25A automotive style fuse. Does that mean that is fused for 12V 25A?
3) 25A would only allow 500mA per port with only 500mA extra to handle startup surge. Does that seem right?
4) Is it likely that the traces would allow more power than 500 mA if the board's total power rating is not exceeded?
More goal is to run more 2PAC and other USB miners as the price is right and I acquire them. I should have asked what fuse was on the board since I have read about other 49 port Block Erupter hubs having 50 or 70A fuses. Does it seem likely that I can run a few higher-power usb devices like 2PAC or Moonlanders on this board?
So they were badly made. Pull that fuse and put in a 20 amp. As they tended to melt.
Asicminer built them. I owned 128 sticks and could run about 40 on three hubs for a total of 120 sticks.
You can pull 1.1 amps on a port if you run about 15 sticks on the hub.
