What kind of problems?
Client being used is bitminter. Have to scan ports multiple times to get most recognized. Can never get all to run. Even when dropped miners down to 30 on 49 port hub. Some will not mine unless moved around etc.
I also can not run an anker hub plugged into same computer as 49 port hub as same issues will affect the anker where some will just not be recognized and or fail during mining.
moved anker to another computer. it works perfectly. move 49 hub to that computer issues again.
also having some miners with issues which I am trying to sort out by rotating them through anker on other computer to find the dead or fringe ones.
I suspect it is the way the hubs are cascaded on the 49 port hub. on OSX I can see the hierarchy of how they are recognized. I also suspect noise issues on the 49 port hub.
All of my equipment gets clean power from online UPS/AVR

I have been in touch with the seller and he will make good as needed. The techie in me just wants to sort out the issue's so I know as close to 100% what is causing it. Just not enough free time.
Sounds like you have a number of problems.
Troubleshooting tips as follows:
1. Test your hardware in this order BE sticks first, usb hubs second, computer hardware third and driver & miner software last
2. When testing BE sticks its not enough to see if they are recognized by the computer, they actually need to be mining before they are proved good
3. When testing usb hubs plug it in empty first then start plugging BE sticks in one by one. Again, its not enough that the sticks are recognized...they need to be mining to show that they are working right
4. There is a myriad of hardware configurations on computers when it comes to usb ports. The number of levels of daisy chaining is just one example of how the usb hardware setup can be different between one computer and another.
5. Lastly there is the driver & miner software. Of course keeping up with the latest versions is always a good idea but I have seen different behavior between versions. The hot-swapping on the latest version of cgminer for example will pick up say 30 of my BE sticks and hot-swap in the last 20 over the course of up to 2-3 minutes and be completely stable after that.
Hope this helps.
