Hi Bin, sorry for the late reply but I was off for easter.

Yes, that's my impression too. That said I can't seem to find the faulty config. Since I wasn't all that clear on my previous mail, this is a VIA805 chip, directly soldered on the board and interfaced with trough RPi4's PCIe bus (the PCIe bus isn't exposed, so it's the only user). The Linux version of this works fine, and is already supported upstream. > Could you please compare all the data structures, with the one set up > by the Linux kernel? I've attached some logs comparing u-boot's and Linux's view of the registers. I dumped them before and after calling the 'enable slot' command. I left all the debuging information just in case it's helpful and also attached some patches to show my changes. Note that I thoughfully compared them myself. The only odd thing I found was "USBSTS: 0x10" (Port Detect Change is set), which isn't the case in Linux. I tried to clear it at different places (before and after changing the individual port status), without effect. That's all. If the data I sent is a little bit too dense, please tell me and I'll remove all the less important stuff :). Regards, Nicolas
