USB mass storage fails to register on kernel 2.6.32

USB mass storage fails to register on kernel 2.6.32

[Paul Sheer]

Hi there,

I have a Samsung Story external USB-2.0 1.5TB drive that fails to
detect as a device in more recent kernel versions. Full kmsg details
are below. Note that a USB thumb drive works fine on my system.
Older kernels work fine with the Samsung also. In terms of which
version of the kernel this stopped working, this I don't know.


uname -a gives:

    Linux version 2.6.32-23-generic (buildd@rothera) (gcc version
    4.4.3 (Ubuntu 4.4.3-4ubuntu5) ) #37-Ubuntu SMP Fri Jun 11
    07:54:58 UTC 2010



My kmsg output when plugging in the drive is as follows:


    <6>[  244.624034] usb 1-10: new high speed USB device using ehci_hcd
and address 3
    <3>[  244.780033] usb 1-10: device descriptor read/64, error -32

    <4>[  245.980413] usb 1-10: no configuration chosen from 0 choices




When plugging in my thumb drive I get the expected results:

Can you bisect this problem maybe?

I would love to but I don't have the time unfortunately.

If someone is interested in fixing this I can send them
a new Samsung Story by mail.

Any takers?

Are you certain this is related to the kernel version and isn't just a 
bad USB connection or something of that sort?  Have you tried plugging 
the Samsung drive into a different computer running a recent kernel?

These -71 errors are what you typically get when a device stops 
responding or the USB signals aren't transmitted properly.

You know, it's not necessary to subscribe to the mailing lists before

patch? Re: USB mass storage fails to register on kernel 2.6.32

[Paul Sheer]

Ok, I changed the cable and it works perfectly.

I suggest the following patch then:

--- ./drivers/usb/core/hub.c 2010-06-11 09:54:26.000000000 +0200
+++ ./drivers/usb/core/hub.c.new 2010-07-04 17:10:28.000000000 +0200
@@ -2777,12 +2777,12 @@
retval = -ENODEV;
goto fail;
}
if (r) {
dev_err(&udev->dev,
- "device descriptor read/64, error %d\n",
- r);
+ "device descriptor read/64, error %d%s\n",
+ r, r == -32 ? ": bad cable?" : "");
retval = -EMSGSIZE;
continue;
}
#undef GET_DESCRIPTOR_BUFSIZE
}

I guess this closes this issue.

Kind regards
