Description Adrian Pilchowiec 2008-08-25 08:38:50 UTC 
Distribution: Fedora
Hardware Environment: Asus F3Sc -> http://www.smolts.org/show?uuid=pub_7bfb182b-dee4-4154-bf48-57bf02e363c6

Problem Description:
When trying to plug PMP Eon Slide-R TC, device is being immediately disconnected, so there's no chance to mount and browse the device, even if it should be working with kernels > 2.4.4 (as declared by producer). I've tried already to add udev rules for this PMP, reformatting the device and few different cables to exclude cabling problem, but all without luck. I don't have also usb hub. On Windows it's just working. Here's what i get from dmesg output:

Please build a kernel with CONFIG_USB_STORAGE_DEBUG enabled and attach 
the resulting dmesg log to the bug report.

Finally I'd managed to attach output from dmesg, I had some problems with BZ's internal error earlier.
Comment 5 Alan Stern 2008-08-27 09:21:25 UTC 
There's a bug in the USB chip on your device; it doesn't respond 
correctly to MODE SENSE requests.  The patch below should work around 
the problem.

Thanks Alan, now it's working almost perfectly.
But now I see a lot of messages like: 

sd 4:0:0:0: [sdb] Result: hostbyte=DID_ERROR 
driverbyte=DRIVER_OK,SUGGEST_RETRY
end_request: I/O error, dev sdb, sector 7422792

sd 4:0:0:0: [sdb] Result: hostbyte=DID_ERROR

Is it some real problem or it just can be ignored ?

uhhh again problem with formatting, sorry for that :/ I don't know what's wrong with my mail client :/ Probably it's some problem with signing messages. I will use web interface until I will fix this issue.
Comment 8 Mohammad Bahathir Hashim 2008-08-28 00:39:47 UTC 
The patch works. But, I got errors during file transfer to the device. To solve the problem, I did

# echo 64 > /sys/block/sdb/device/max_sectors

/dev/sdb is the MP3/4 device.

I tried with 128 but not working.

Confirmed. Adding those lines 

+
+UNUSUAL_DEV(  0x071b, 0x3203, 0x0000, 0x0000,
+               "RockChip",
+               "ROCK MP3",
+               US_SC_DEVICE, US_PR_DEVICE, NULL,
+               US_FL_MAX_SECTORS_64 ),
+

to patch proposed by Alan solved problem for me. Now everything works just 
perfect.

Patch for Rockchip MP3

Just to confirm, is this the patch that works?  If it is, I will submit it.
Comment 11 Adrian Pilchowiec 2008-09-04 02:50:12 UTC 
Yes, that's this one. Everything works with it.

It does not work on my GNU/Linux :(

But the previous patch in comment #5 works, but have add script to change max_sectors to 64 in udev script.
Comment 13 Alan Stern 2008-09-08 07:58:08 UTC 
Mohammad, I don't understand.  The patch in comment #10 is exactly the same as the patch in comment #5 except that it also sets max_sectors to 64.

So what's going wrong?
Comment 14 Mohammad Bahathir Hashim 2008-09-08 19:22:26 UTC 
Yes, but, with patch #10, my GNU/Linux system can detect the device but cannot mount it, and disconnected from USB system. Also /sys/block/%k/device/max_sectors value still 240 and did not change to 64.
I will send debug result in short while.

TQ.

dmesg output

Here is the dmesg, after applying patch #10 and mount the device.

lsusb output.

Comment 17 Alan Stern 2008-09-09 08:33:35 UTC 
The dmesg log in #15 indicates that you did not have patch #10 installed.  You can confirm this by looking at the file in /proc/scsi/usb-storage.
Comment 18 Mohammad Bahathir Hashim 2008-09-09 20:17:05 UTC 
Confirmed! Patch #10 works. I forgot to changed 0x0100,0x0100 portion from the original code. I did the patches manually, and sometime I missed it... My bad... Sorry.

Thanks you very much.

patch submitted?
Comment 20 Alan Stern 2008-09-28 08:32:24 UTC 
Not only has it been submitted, it has been accepted and is already in Linus's current tree.  It will appear in 2.6.27-rc8.  This bug report can be closed.
Comment 21 Greg Kroah-Hartman 2008-09-29 08:47:38 UTC 
ok, closing out.
