[SOLVED] USB flash not showing up

Tue Oct 25, 2016 8:43 pm

Hello,

I've just purchased my first Mikrotik device (CRS109-8G-1S-2HnD-IN) and I'm having trouble seeing the attached USB flash drives via the OTG cable. I've tried with 3 different USB drives and none of them show up in
/disk print
nor in WebFig. Even tried
/system routerboard usb set usb-mode=force-host
and still no luck.
One thing I saw that after connecting the flash drive, the LED from the drive lights up for 2 seconds and then it goes off.
I'm running the latest current release (6.37.1).
Any clues on what may be the issue?

Thanks!

Can you check you are running the latest firmware on the CRS device?

Does the device show up in the USB list?
/system resource usb print
MTCNA, MTCRE, MTCINE, MTCTCE, MTCIPv6E, MTCUME

Are your devices USB 3.0 or 2.0?

I'm having a similar issue and currently it seems that all USB 2.0 flash drives that I have are working great, but any of the USB 3.0 drives are not recognized anywhere, including 'system resource usb print'. I've also tried automatic and force-host modes.
Reformatted the all the disks in virtually every possible way but still no luck.

Working:
4 different USB2.0 drives from sizes 4GB to 8GB

Not working:
2 different models (and two of each model) USB3.0 drives. Sizes 16GB and 128GB

So it's probably either USB2.0/USB3.0 or drive size that's currently limiting. But I have RB3011, which should have USB3.0 support.

Yes, it shows up.
/system resource usb print

I have 2 USB2.0 and one USB 3.0. None of them work.

Apparently, rebooting the router with the USB flash connected solved the issue. After it came up again, I could see anf format the device. I guess it doesn't have hotplug capabilities.
