Still an issue in 4.18.9... However, I have 2 different USB3 adapters with the same chipset. One is the Plugable USB3-E1000 (which has the problem within a second when running iperf). The other one is a cheap Amazon Basics USB3 Gigabit Ethernet Adapter which runs perfectly fine. Both use the same driver. I don't have any USB2 ports on my Dell laptop so I can't test if USB2 is OK.

Plugging on USB2 port, exact same situation otherwise, works well. This is reproducible 3 out of 4 attempts. Machine has 2 USB3 ports on the left, 2 USB2 ports on the right. ### When working (USB2 port) * ethernet auto-negociation is fast * mii-tool is fast (typical 0.05s) * few lines in dmesg * good performance ### When failing : * ethernet auto-negociation fails, then sometimes eventually works * mii-tool is slow (10s of seconds instead of 0.05s) time sudo mii-tool eth0: no link eth1: 10 Mbit, half duplex, no link real 0m40.014s user 0m0.013s sys 0m0.006s time sudo mii-tool eth0: no link eth1: 10 Mbit, half duplex, no link real 0m50.015s user 0m0.011s sys 0m0.011s time sudo mii-tool eth0: no link eth1: negotiated 100baseTx-FD, link ok real 0m10.051s user 0m0.000s sys 0m0.012s But on some attempts mii-tool is fast... time sudo mii-tool eth0: no link eth1: negotiated 100baseTx-FD, link ok real 0m0.057s user 0m0.011s sys 0m0.012s * DHCP eventually completes (after about 30 seconds) then ethernet works. * whole system behaviour feels a little sluggish (not very clear, though) * mii-tool still slow (10s of seconds instead of 0.05s) ## dmesg when failing Full dmesg attached.
