All downstream devices have messages similar to usb 1-1.4.4.4.4.2: not running at top speed; connect to a high speed hub. Why is the first external hub in the chain at full-speed? This limits the entire bus segment to 12mbit/s, and in practice the useable bandwidth will be even lower because of the vast numbers of endpoints that will be active (i.e. polled regularly).

3 years ago The TUSB2046B only supports full speed. So it is to be expected that it only runs at 12 MBit/s. The 48 serial ports running at 115200 kBit/s would in total need 5529600 kBit/s. That is less than half of the gross USB speed so there is still more than 50% left for the USB overhead. And the crash happens even when there is nothing actually transmitting or receiving on those ports.
Also as I wrote in the bug report, the crash doesn't happen when the serial port chain is connected to my notebook. So it is something specific to the Raspi.

3 years ago Weird hardware design decisions aside, the controller is crashing - not the kernel. The clue is

It'll probably be easier/cheaper to buy a boatload of FT4232H adapters to replicate the issue rather than try and source this specialist hardware.

3 years ago So the VL805 connected to the PCIe bridge crashes or enters a state that isn't handled? I'm actually surprised to learn that this USB controller has a firmware. As a firmware developer myself I know how often limits in there are not properly checked because "that can never happen"...
You can't simply buy this HW, you would have to build it yourself, it is open hardware. And one of the reasons to use a full speed hub chip (aside from the simpler board layout) is probably that the chances of getting high speed USB reliably across pin connectors are low.
So yes, buying 9 FT4232H adapters (e.g. Digitus DA-70159) and a few switches is the only other way to replicate it. Still quite the investment, though. But definitely faster than getting the PCBs produced and assembled. I'm happy to do whatever is needed to debug this. Though that has to wait until after New Years.

3 years ago The fact that a read returned a completion timeout indicates an access to one of the xhci controller registers (nominally hardware) failed.
It's not clear what the interaction is between the firmware and controller hardware in this case. We know it has supervisory functions and can e.g. write to power state control registers inside the PCIe endpoint based on controller activity, but any clarification would have to come from VIA.

I then tested with a Rpi 1 (with some rather old Linux on it) and there it was working with the full 48 port chain, pretty slow but at least no hangs or crash.
Thinking that the Rpi 3B+ had a similar USB layout to the Rpi 1 (i.e. no PCIe device) I tried that one and the result was even worse than with the Rpi 4. The Rpi 3B+ silently hangs after about 10-20 seconds after connecting the chain. The only indication of a problem was in dmesg before the system got unresponsive:

[ 2050.880847] usb 1-1.2.4.4.4.1: Detected FT4232HReducing the chain to 36 ports everything was fine on the Rpi3B+. Trying to attach the last 12 ports separately again triggered the memory allocation error. After some searching the solution was simple: Adding _coherentpool=2M to cmdline.txt allows the use of all 48 ports on the Rpi3B+.
Describe the bug The system prints kernel messages about an unhandled fault when accessing more than 34 serial ports (ttyUSB).
