Today I installed the new SIIG pcie 4 port USB 3 adapter into the Lenovo shitbox I bought a few years back.
Initially, I was thinking I would gain 4 ports, but alas ... the provisioning on this piss poor Lenovo effort already utilized a 2 port pcie in the destination slot.
At least I was able to double the high speed ports.
So looking the device over I noticed the "notebook in a case" design of the crappy Lenovo workstation would not lend itself to the large mounting plate already attached so I removed it and installed the smaller one.
I reseated the board in the pcie slot and rechecked everything and applied liberal compressed air dust removal prior to affixing the mounting screws.
After giving it one more inspection for good measure I reassembled the case, reattached the cables and looked everything over one last time.
Anyway things loaded like a charm first time. I gave it a few moments and restarted the machine a few times to attain that "last known good configuration" nirvana MCSE training taught me regarding ...
And voila, I went from 2 USB 3 ports to 4 and now everything has a port with a remainder of one for future reference.
The main things are to look things over, exercise static control and reasonable caution, and recheck prior to applying power.
I needed this upgrade badly.
Final word of caution:
Never buy anything from Lenovo or Frys Electronics because they're both companies you're better off without. Nothing but disappointment and trouble. No wonder Dell is making a haul.
