Subject: nothing happens upon SD card insertion (Asus Zenbook UM425IA, RTS522A)
Date: Sat, 25 Dec 2021 11:45:57 +0100 [thread overview]
Message-ID: <sq6sp6$cs9$1@ciao.gmane.io> (raw)
Hello,
I have an Asus Zenbook UM425IA laptop with Realtek RTS522A card reader:
02:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS522A
PCI Express Card Reader (rev 01)
Almost every time when I insert a card into it, nothing happens - no
dmesg message or anything.
echo 1 | sudo tee -a /sys/kernel/debug/tracing/events/mmc/enable
sudo cat /sys/kernel/debug/tracing/trace_pipe > mmc_trace.txt
also results in an empty file. If I am lucky, the card will be detected
after some delay and the following will appear in the log:
Dez 25 11:34:41 snowball3 kernel: mmc0: cannot verify signal voltage switch
Dez 25 11:34:41 snowball3 kernel: mmc0: new ultra high speed SDR50 SDHC
card at address aaaa
Dez 25 11:34:41 snowball3 kernel: mmcblk0: mmc0:aaaa SL32G 29.7 GiB
Dez 25 11:34:41 snowball3 kernel: mmcblk0: p1
How can I investigate this further? As things stand now, the reader is
almost unusable. I am using 5.15.11-200.s0ix01.fc35.x86_64 kernel. Thank
you in advance.
Best regards,
Julian
