Hi,
I came across a problem with an USB SD card reader apparently causing
USB resets and corrupting data on the card.
The reader in question is a very cheap:
14cd:1212 Super Top microSD card reader (SY-T18)
The card is an old SDHC, 32 GB, Sandisk brand.
The problems don't seem to exist now if I connect the reader to an
EHCI-equipped machine (an old Core2 duo + ICH10). I can read and write
MBs of data, however older logs suggest that this computer also had the
issue in the past (with Linux 4.6.3-300.fc24.x86_64, with both EHCI and UHCI).
I can't use it with an XHCI. Both:
Intel Corp 8 Series/C220 Series Chipset Family USB xHCI (rev 04) (prog-if 30 [XHCI])
(SandyBridge laptop with only USB2.0 connectors) and:
Intel Corp Sunrise Point-H USB 3.0 xHCI Controller (rev 31)
(a Skylake + Z170 and USB3, though the reader is USB2) have the issue.
I have spotted the following writted to the SD card, I guess it's some
USB mass storage write command:
3d085000 55 53 42 43 ca 08 00 00 00 e0 01 00 00 00 0a 2a |USBC...........*|
3d085010 00 00 1e 83 70 00 00 f0 00 00 00 00 00 00 00 b2 |....p...........|
3d085020 2d 00 38 00 a9 c8 f4 ab 10 8d cc 39 e1 8f 43 45 |-.8........9..CE|
I think the problem doesn't manifest itself if I don't write (RO mount)
to the SD card. However, even light writes seem to trigger the issue.
The kernels are basically recent Fedora, 4.7.4-200.fc24.x86_64,
4.7.9-200.fc24.x86_64 but it seems e.g. 4.6.3-300.fc24.x86_64 was also
affected. The one which doesn't cause problems now (EHCI) is
4.7.2-201.fc24.x86_64 (though EHCI did cause problems previously).
Could it be faulty hw?
What can I do with this?
