From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Help Solving a USB Expansion Card Firmware Issue (lemmy.ml)

I recently got a FebSmart model FS-U304C-Pro. Supposedly, it's based off of the RENESAS UPD720201 host controller, which uses the xhci-pci-renesas firmware module. The manual says toward should work out of the box with "most" Linux kernels.

Unfortunately, when I tried to install the card into my system, it did not function. The card gets registered by lspci, and the kernel module shows up underneath it. The issue is that the usbs do not communicate through the card.

I tried looking at dmesg and I found what might be my issue:

xhci-pci-renesas 000:0*:00.0: Download to external ROM TO:0

xhci-pci-renesas 000:0*:00.0: Timeout for Set DATAX step: 2

xhci-pci-renesas 000:0*:00.0: Firmware Download Step 2 failed at position 8 bytes with error (-110).

xhci-pci-renesas 000:0*:00.0: firmware failed to download (z110).

xhci-pci-renesas 000:0*:00.0: probe with driver xhci-pci-renesas failed with error -110

I have tried reinstalling my firmware modules, updating my system, andmoving the card to my other x1 slot.

Is there any way I can solve this issue locally before I either send this to issue to a bug tracker or send this card back? Also, I use Arch btw.

There you go. That's a good entry point to figure this out.

Identify which port you're plugging this card into and turn it's settings to the slowest option. I'm almost certain the speed is being negotiated on auto incorrectly.

If this works to get the firmware loaded, then you can go back and step the speeds up until it breaks, and then you know where the limit is.

None of the settings have worked, but I did find 2 interesting settings hanging out in bios.

Would either changing the South Bridge speed or turning on the Compatibility Support Module (CSM) do anything?

Those could impact larger groups of things, but right now you're just interested in making this work. I'm pretty sure this board is negotiating a faster connection than it's capable of, so maybe try it out and see if it works.

Well one of those options affected my ability to connect to my monitor. The issue was not resolved though, and I don't feel like clearing my cmos again to see which setting exactly caused the issue
