Received new UH720.  Several issues:

• Will not read some USB 3.0 thumb drives.  Various sizes from 32 Gb to 256 Gb.  Drives don't show up in My Computer when connected through hub.  If same drives are plugged directly in to computers USB port they work fine.
• Will occassionally lock computer or temporarily slow down computer (mouse/keyboard becomes unresponsive).  When hub is unplugged, computer returns to normal
• Charging ports will not charge all items.  Example: Will charge iPhone 7, but won't charge Samsung Galaxy S8+

Had a different hub connected to this same computer, and none of the issues listed above were present, using same exact devices.

Anyone else experience similar issues or have advice?  Contacted TP Link and they were of no help.  Said call would be escalated and that I should hear back from someone within 24 hours, but I haven't heard anything.

Thanks in advance!
