Odd problem with Huawei Matebook D USB ports

117 65 April 10, 2019 at 02:05 AM
I have the Matebook D AMD version and I'm having issues with the USB ports. I have an external 4tb 2.5" seagate hdd in a third party Startech enclosure... So the problem is I hook it up to the USB 3.0 type A port on the left side and it just continually connects and reconnects and won't ever get recognized. I hook it up to the USB C port via an adapter from type C to type A and the same thing happens. It works just fine on the right side USB 2.0 port but obviously I want USB 3.0... The odd thing is that I bought a HooToo usb C hub and hook that up to the C port and then plug the HDD into that and it works fine, and that is without plugging in the power adapter into the Hub... Can't understand how it would work with the hub and not without the hub if it was a power issue with the drive not getting enough juice.. Any ideas?

Another strange thing is that it lists the hub as USB 2.0 Billboard but then lists the drive as USB 3.1 device...

Most likely a voltage/amp difference in the ports.. "google"

"Unfortunately, one of the Type-A ports is USB 2.0 and the other is USB 3.0, and Huawei doesn't provide any distinction between the two. Typically, the USB 3.0 port would be blue, or there would be the 'SS' logo to indicate it, but there are no color coordination or labels here. Upon inspecting the ports, you'll see that the one on the right is actually the USB 3.0 port, but I don't expect most end users to know the difference."

Concur that power is the most obvious cause, though it's not the only possibility. That USB-C hub you've got might be negotiating a higher power level from the USB-C port its attached to, and then providing it to downstream devices (possibly beyond the normal max power levels for traditional USB devices). So it may be as if you've plugged in external power.

Yeah and I submitted an e-mail to Huawei and they said "We understand that you would like to use your 4TB 2.5 with your MateBook D using the USB 3.0 port. Because of this reason, allow us to inform you that we have sent your issue to our research and development department in order for them to verify an available solution for this particular situation."

So they said they would get back to me... People who say their support sucks is wrong btw, they reply very fast and even replaced my USB-C cable overnight... Anyway thanks for the help, I might just buy a 256GB flash drive for the backup...
