I tried to connect a usb HUB to C31MINIDOCK4KPD HUB but it didn’t recognize it on the phone. Is it because I used a cheap 2$ usb HUB?
Does the Hub require to be powered?
Yes, it requires to be powered.
To clarify that question … a USB device is either
- bus-powered, or
- self-powered (and in the case of a USB hub that is often just described as “powered”).
Was the dock on mains power? I suggest that particularly if you are going to chain USB hubs then the dock should be on mains power so that there is enough power available to
- power the dock itself (including the built-in functions of HDMI output and ethernet)
- power the hub that is connected to the dock
- power all the actual USB devices that might be connected to the dock
- charge the Librem 5 (or at least maintain the level of charge).
Not putting the dock on mains power and trying to power all that from the Librem 5 might be a problem.
lsusb is your friend. Before and after plugging in the 2$ USB hub.
For fault isolation, confirm that the 2$ USB hub works at all e.g. when connected directly to the phone or better still when connected directly to a random computer.
the 2$ USB hub only recognizes windows partitions
OK, that must be a new low in lameness.
On the face of it, I don’t understand how that is even possible. A hub shouldn’t care what is on a USB mass storage class device. A USB mass storage class device is an array of blocks. What partition table is used and what file systems are on each partition shouldn’t matter. That should apply even when a dock (kind of a hub) has a built-in (u)SD card reader, as some do, even though the interface from the dock to the card is then probably an SD interface.
However I understand that cheap and nasty implementations never fail to surprise.
For $2 it’s probably not worth persevering with.
Did you find a hub that works? I just bought the cheapest I could find (Lemorele brand) to play with it. It works briefly, but the monitor keeps flicking on and off. The wireless mouse doesn’t work either. It is a powered hub, but that doesn’t seem to make a difference.
The official unofficial answer is here: https://source.puri.sm/Librem5/community-wiki/-/wikis/Tested%20Accessories#hubs i.e. where customers document their experiences, success or fail. It probably isn’t completely up to date though.
I’ve actually gone off in the “lapdock” direction.
Also Purism sells one in the store.
