Windows 10: need to connect lots of USB to PC

Hello all and thanks for your help,

I have a DELL 7050 with 2 USB's PCI express cards connected to it.

I have 12 DIGI HUBPORT /14 USB racks.

i want to connect those racks to my DELL 7050.

when connecting the 1st rack to the PCI express card all is good. when connecting the 2nd rack to same PCI card i start getting those errors:

1) Not enough USB controller resources
2) USB Device bot recognized.

when connecting those racks to the on-board USB's, i start getting those errors when i connect the 3rd rack (the first 2 racks are working well).

when those errors are starting to appear, at the device manager i see device not recognized.
when i see the device not recognized in device manager, it is not the whole rack. I mean, if i connect 1st rack with 14 usb connectors, i see 14 new com ports in device manager, when i connect the 2nd rack, i start getting those errors, but in device manager i don't have 14 device not recognized, but i'm getting, lets say, 10 new com ports and 4 device not recognized.

I know that the address that a USB is getting is 7 bits long, meaning you can have up to 127 usb devices. but is that for 1 USB connector or for the whole connectors combine? but I'm getting this errors when connecting only 2 racks (28 devices).

how can i connect all my devices, or does some 1 knows how to connect 12 racks*14 devices each rack to a single PC? (if possible).

Thanks

:)

 

PC Build Steps

Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval

• Install system in case
  • Remember to connect SSD and optical to same SATA ports on motherboard
• Turn on PC
• setup HDD
• run blend test in prime95 for 30-60 min
  • run realtemp at the same time

• While in Prime95 test
  • if CPU goes above 70c in RealTemp, I have a leaky CPU
  • if my system locks up or blue screens, there is an instability in the system somewhere
  • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!

What do you guys think??
