This is crazy. Let me describe a bit more in detail. I happen to have two basically identical living locations, about 200km away from each other. Work equipment is identical – I use 2 100% identical UHD displays, the exact same mouse at each location. Well, the routers are different and thus WLAN is different, too. In both locations, the routers are exactly 1meter away from laptop and docking station – in one location to the left, and in the other to the right. That’s all which is different, everything else is the same.
Now, I also have 2 identical docking stations — I thought one is defective following above malfunctioning USB port report. Two days ago, I reported the “new” dock to be working, but the Logitech dongle didn’t. After submitting the report, I checked the “old” dock … and it had the same behaviour (USB sticks work, Logitech doesn’t – not yet check with extension cable). So, in the first flat both docks WORK PARTLY with USB. Today, I reverted to the second flat. This time with both docks in my luggage. Very surprisingly: BOTH docking again show the same behaviour: both DO NOT WORK AT ALL with USB. Neither does Logitech dongle, nor does any available stick. Extension cable makes no difference.
Originally, I indented to buy either 1 or 2 identical docks (as I did buy 2 identical monitors, too), but I need USB ports to work with each dock. Or, in other words: in each location.
I am running out of ideas why both docks work in flat 1 and both don’t work properly in the other flat, at identical setups. Differences which come to my mind: flat 1 sits on 200m higher altitude 🙂 and flat 2 is in use only Mon-Thu 🙂 WTF?! I am used to do IT troubleshooting (mainly on software side), but I have run out of ideas. If I don’t find out, I will return 1 dock and keep only 1 (if Logitech dongle works in location 1 with extension cable) instead of both units … 🙁
