#Not sure if USB is damaged on my rM2

I'm having a hard time figuring out if the usb port on my rM2 is damaged.
Charging works fine, but when I plug it into any computer, that is a varried physical machine, os linux & windows and cables, nothing gets reported.
On Linux, dmesg shows zero activity, lsusb reports nothing.
When I go into Settings -> General -> Storage the toggle for the usb web interface shows up when i plug the device in, but it does the same when using a charger. The slider is immovable.
I bought the device unsed a few days ago and everything else works perfectly fine.
I was hoping to unlock ssh.
The port it self looks mostly fine, intact but i sported a small brown spot which makes me worry about corrision of some sorts.

This is also what you would see if you usb cable does not carry data - try another cable.

i tried many cables, including proper data ones
I also verified if those cables work with other devices and they work perfectly fine for data
also tried all the orientations
tried c to a and c to c

My next suggestions would be a reboot, a software update or a full recovery - unless you just need to clean the corroded usb port.
(there is a way of getting the log files out of the device without ssh access, but it's using http://10.11.99.1/logs, so you'd need the usb connection to work.

You're not so lucky, that the ssh is already enabled, so you can connect through wifi?

Yes, and it's not easy, so you probably want to look at the physical port first

olive valve
#

im not sure if its corrosion or just smt inside, i tried to carefully poke it but doesnt seem to go away, tbf my method may have been mute

Yes, and if it's the port it wont help anything either.

olive valve
#

yeah

crisp rune
#

Does you device list the 10.11.99.1 ip under Help > Copyright and licenses when you plug it in (a long shot, it shouldn't if it doesn't show up on dmesg)?

#

(you need to reopen the page a few seconds after attaching the cable)

olive valve
#

nope, just its ip in my network

#

the one thing i've also been considering, alltrough i would like to avoid it at all cost is just opening the device up

crisp rune
#

It's not that hard opening the device, but it has been reported to be extremely difficult to reassemble it in a nice looking way (it's not just removing a few screws, or softing a bit of glue in one corner)

olive valve
#

yeah i looked into it
it would kinda suck to have it look all crooked afterwards

crisp rune
#

Clean the port first (isopropyl alcohol?),
Before opening it up, you could also try this: Do >= 2 software updates, and a factory reset - that will leave your file system as if it was a new device, to make sure it's nothing software related - then you'd need to fix the port (unless someone else have better ideas than me - usually there's most activity in this server in 5-10 hours from now)

olive valve
#

how does one force a software update?

crisp rune
#

Without ssh access you can't. But you could enroll in the beta programme, as that has more updates (but without ssh access you can't downgrade, so make your choice wisely). Currently the newest beta and the newest release is the same software version.

olive valve
#

welp, i'll try cleaning the port a bitmore
i'll likely report back later (unless i'll make it work somehow then i'll tell directly)

unfortunatly that didnt work :/

crisp rune
#

Tried a different computer and different cables (and different combinations already)? Not all linux distros connects to the usb ethernet adapter by default, so it could be worth a try, if you have an alternative.

olive valve
#

yeah i did that

#

all of that
even tried a windows machine

#

and again like dmesg doesnt even show any indication of something being plugged in :/

@olive valve did you find a solution to this problem? I have the same issue and I'm going to try cleaning my port this afternoon
