When I read it, it said: CONFIG_BLK_DEV_UB: This driver supports certain USB attached storage devices such as flash keys. If unsure, say N. which sounded potentially useful, and certainly didn't give the impression that the driver was likely to perform terribly in common cases (i.e. when using an external drive). The sample Kconfig warnings I saw posted later in this thread would certainly have given enough information to know to avoid the driver, though if true, this might be even clearer: Note: this driver does not coexist well with usb-storage, and usb-storage is is often the best driver for common devices like external drive enclosures. At the moment, usb-storage may peform dramatically better for those devices. If you're not certain you need this driver, you should probably say 'N' here, and choose usb-storage instead. -- Rob Browning rlb @defaultvalue.org and @debian.org; previously @cs.utexas.edu GPG starting 2002-11-03 = 14DD 432F AE39 534D B592 F9A0 25C8 D377 8C7E 73A4
