Barebox version: 2020.07.0
Hardware: i.MX6 ULL with external Microchip USB Hub attached
I got a bug report that some newer USB memory sticks do not work with
barebox. While with barebox-2020.01 these devices are not recognized at all, in
barebox-2020.07 I get at least some warnings:
# usb

Beside the USB memory stick, also one of the hub's internal
devices is not recognized correctly. The full log output with
global.loglevel=7 is attached. The first error seems to appear
in line 233. The USB device descriptor cannot be read:

Under Linux (on the same device), the USB drives work without any noticeable problems:
Linux messages (v5.4):

An usbmon capture for Linux is also attached (USB memory stick is plugged in at
about packet 99).
Any hints how I can debug this problem. I've almost now knowledge about USB...
regards
Christian

I checked again with an older release of barebox (2019-06). With this version,
the USB drive is detected:

Also mounting the drive works fine. So I guess that this problem may have been
introduced here:
b1d9837182 ("usb: Change power-on / scanning timeout handling")

Before guessing further could you verify that exactly this commit breaks
your setup? There are a few more changes in the area that could be the
culprit.

sorry, that was nonprofessional. In the meantime, I got some new findings:
- v2019.06 is the last release were the device is detected
- reverting b1d9837182 ("usb: Change power-on / scanning timeout handling")
doesn't change anything (so it's not related to this problem)
- the problem was definitely introduced in
6044d6c08e ("usb: host: ehci: Use to USBSTS to wait for transfer completion")
Debugging with and without 6044d6c08e showed that waiting for USBSTS:INT
is not sufficient as QT_TOKEN_STATUS_ACTIVE is still set after this. Turning
the dev_dbg() into an dev_err() clearly shows this:

It seems that I can take multiple USBINTs until QT_TOKEN_STATUS_ACTIVE is
cleared. The following snippet works fine for me:
volatile struct qTD *vtd;
...
vtd = td;
do {
ret = handshake(&ehci->hcor->or_usbsts, STS_USBINT, STS_USBINT,
timeout_ms * 1000);
if (ret < 0) {
dev_err(ehci->dev, "handshake failed: %d\n", ret);
ehci_enable_async_schedule(ehci, false);
ehci_writel(&qh->qt_token, 0);
return -ETIMEDOUT;
}
token = hc32_to_cpu(vtd->qt_token);
} while (token & QT_TOKEN_STATUS_ACTIVE);
There is probably no benefit left compared to the version prior 6044d6c08e, so
if there is not better way to do this, I would propose to revert 6044d6c08e.
regards
Christian

I am fine with reverting 6044d6c08e, but let's give Andrey some time to
react before doing this.

Since 6044d6c08e, some USB mass storage devices (in my case some USB
memory sticks and one SD card reader) are not detected anymore. Waiting
once for USBSTS::USBINT is not sufficient as it takes multiple USBINT
events until QT_TOKEN_STATUS_ACTIVE is cleared.
Fixes: 6044d6c08e ("usb: host: ehci: Use to USBSTS to wait for transfer completion")

I'll be on holiday next week. So it send it now before it gets lost.
