USB 3.0 and the 127 device limit.
According to the ads about USB 3.0, you are supposed to be able to use up to 127 devices. NOT SO! Windows 10 Pro craps out around 14 HDD when using USB 3.0. Bummer!!! Reverting to USB 2.0 allows at least 20 HDD drives. That is as many as I have connected and they all work. Using USB 3.0, the system refuses to accommodate more than 14 HDD! Too bad reality does not match up with the ad copy!! Cost a far amount of time and money to make this discovery. Nothing in the information provided by the suppliers mentions the USB 3.0 limitation. You find the limitation when Windows 10 says ".....Not enough USB resources The controller does not have enough resources for this device......" Very very very annoying. My solution was to change to USB 2.0 hubs which have allowed all of my USB HDDs to attach to the PC and function, using slower USB 2.0 speeds. As I said very very very very annoying!!!!
