Lenovo USB 3.0 dock - swap or replace?
 

After a year of working seamlessly my computer now sounds like a pinball machine of dropping & adding peripherals - troubleshooting has remedied nothing and it's getting worse (details here: http://www.displaylink.org/forum/showthread.php?t=62699 )

Can i hear opinions on whether i should try a new Lenovo USB 3.0 dock assuming it's a hardware issue (can't imagine this working), or can someone recommend a non-OEM USB dock that works reliably? Needs to be compatible with Carbon X1 old generation (2013)

Amazon has the Plugable UD-3900 ranked #1 with 4.5 stars; Anker USB 3.0 also has 4.5 stars.

Thanks
