Nemo hangs when PTP is unable to return friendly name

[Mario Olivio Flores]

NOTE: I think this is probably so low priority it may never make sense to fix, but I wanted to document it in case others are stumbling across this and to ensure a web search leads those users somewhere.

Expected behavior: Nemo to open with a USB device connected.

# Actual Behavior

When a specific low-quality, proprietary tablet device is connected to my computer, Nemo rarely opens. Nemo usually times out, but it occasionally opens after a multi-minute delay. Also, disconnecting the low-quality hardware resolves the issue. I'm guessing that Nemo is blocked attempting to fetch the "friendly device name" in the logs below.

# Logs

Doing my best to identify some logging, I typically see these symptoms:

when attempting to launch Nemo from the terminal: `Could not register Nemo as a remote: Timeout was reached`

in Syslog:
```
Nov 12 20:51:43 dell-XPS-15-7590 gvfsd[542176]: Error 2: PTP Layer error 02ff: Error getting friendlyname.

```

[v. p. (v1nce29)]

Same here.
Except I didn't get the text `Could not register Nemo as a remote: Timeout was reached`

Plus nemo grabs the keyboard access for its own exclusive use.
So, for lambda user, it looks like the only solution is to switch off your computer.

ubuntu 18.04
