--- Comment #22 from Hannes Reinecke ---
Which translates to:
Byte 0, bit 5-7: Peripheral qualifier: 0
Byte 0, bit 0-4: Peripheral device type: 0
Byte 1: Page code: 0x80
Byte 2-3: Page length: 0x202 = 514
Byte 4-: Product Serial Number:
And the spec says:
The PRODUCT SERIAL NUMBER field contains right-aligned ASCII data.
0x1f is _not_ ASCII. So the field is garbage anyway.
And you can already spot the issue with the output:
- There's a wrap at 0x200; the line in 0x200 looks identical to the first line.
I _bet_ if you ask the device to provide you with 1k of data you'd be getting
the same output twice ...
- It looks as if they've stored the information in a 512-byte buffer (ie one
block), but fail to set the correct offsets.
- Surprisingly enough, '0x1f' is roughly the size of the following
right-aligned
ASCII data. One more indicator for crappy USB information.
Anyway, it's garbage. But I've fixed now the sg3_utils to not display any
information for invalid fields.
