I think this is what hurts you...
I compared linux-2.4.19 and linux-2-5-70 /drivers/usb/storage/unusual_devs.h
/* This entry is needed because the device reports Sub=ff */
-UNUSUAL_DEV( 0x054c, 0x0010, 0x0106, 0x0422,
+UNUSUAL_DEV( 0x054c, 0x0010, 0x0106, 0x0450,
"Sony",
- "DSC-S30/S70/S75/505V/F505/F707",
+ "DSC-S30/S70/S75/505V/F505/F707/F717/P8",
US_SC_SCSI, US_PR_CB, NULL,
US_FL_SINGLE_LUN | US_FL_START_STOP | US_FL_MODE_XLATE ),
If I remember correctly the change from 0x0422 to 0x450 is the upper limit
device version accepted. But in this case it could be the other way around -
depends on what kernel you use...
There are lots of other differences...
Maybe a change in strategy is needed?
(question for linux-usb-devel, it was discussed recently...)
Leave the device version open for broken vendor:product pairs...
