I have an external 4-way USB3.0 hub (I actually have two of them) That do not behave as expected.
It is an XCD XCDESSUSBH4BK. It is unpowered. I am on fedora 34, kernel 5.13.8-200.fc34.x86_64
For starters, I found that attaching a USB SSD does not allow booting from it.
I then found that when attaching my phone it is not recognized.
I searched the hub model and IDs but did not find relevant information.
Is there an official list of supported hubs (or devices)?
Here is what it looks like.
When the hub is attached (no phone) I see
Bus 001 Device 048: ID 0bda:5411 Realtek Semiconductor Corp. RTS5411 Hub
and
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/16p, 480M
|__ Port 5: Dev 5, If 0, Class=Hub, Driver=hub/4p, 480M
|__ Port 2: Dev 48, If 0, Class=Hub, Driver=hub/4p, 480M
Attaching the phone does not add a device.
Detaching/attaching the hub (with the phone already plugged in) I get
Bus 001 Device 052: ID 04e8:6860 Samsung Electronics Co., Ltd Galaxy A5 (MTP)
Bus 001 Device 051: ID 0bda:5411 Realtek Semiconductor Corp. RTS5411 Hub
and
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/16p, 480M
|__ Port 5: Dev 5, If 0, Class=Hub, Driver=hub/4p, 480M
|__ Port 2: Dev 51, If 0, Class=Hub, Driver=hub/4p, 480M
|__ Port 1: Dev 52, If 1, Class=Communications, Driver=cdc_acm, 480M
|__ Port 1: Dev 52, If 2, Class=CDC Data, Driver=cdc_acm, 480M
|__ Port 1: Dev 52, If 0, Class=Imaging, Driver=, 480M
|__ Port 1: Dev 52, If 3, Class=Vendor Specific Class, Driver=, 480M
and the phone is recognized and accessible as MTP device.
Here are the logged messages for the two situations.
