Hi, I am very satisfied with this router and the brand in particular, easy gui on opewrt and great price performance ratio, but ... I didn't realize it only had one usb port. I was using two mirrored hdds with rsync and tried: 1) a hub, and it would only see my drive on the first output; 2) a charge+usb splitter on the power usb c. Obvious checks: both drives work on port A, I tried force uuid on luci; the splitter is 25 watts, the router 5V 3 A, and I also tried a 5V 4A power supply. Browsing the forums I looked at /sys/class/gpio but I don't want to risk resetting it for two days, maybe someone here can tell me in one line and for the MT3000. Thanks
Note: lsusb -v shows 2 USB devices, but the second one had a "can't get qualifier/descriptor" error immediately after a minimal power value, 5 times lower than the other device.
These problems are common especially with spinner hard drives and not SSD's the drives; especially spinning ones pull more power than the USB port can output. Make sure you get a USB powered hub with external power and one rated with the necessary output of the drives.
Thanks, I had thought about that, but I wanted to minimize the bulk of the charger and hub in proportion to the size of the router, which is in an antique-style room. If I could make the power port bidirectional, or increase the power of the other one via GPIO, that would be better. Otherwise, I'll have to come up with something to make better use of the power supplies.
The router can only be regarded as a light NAS, but does not have the ability to be regarded as an all-round NAS.
That is designed to drive small things like USB disks, dongles, etc.
When connecting to the mobile hard drive (2.5 '/3.5 '), add the external power will be more secure.
Thank you for your official response. In fact, even on the MediaTek dga4132, which had a much higher power supply, the disks on 3.0 had a very slow read/write speed compared to the connection with the PC. I have already ordered a 15W hub, and I will remedy the bulkiness with a single 60W power supply with splitters and adapters for GPON, hub, router, and occasional devices, at a distance from overload.
