Bug#279696: ub driver:Issues with makedev, improper major number and slow performance
There is a bug on makedev (#278237) concerning the lack of support for
the new and experimental ub driver. This driver was prematurely
released using an experimental major number (125/b) and about 9 days
later was assigned a major number (180/b). Until makedev is updated,
the device files must be created manually (not too big of a deal, if you
realize the problem and the solution).
More importantly, this is a low performance driver designed for low
performance flash drives however many USB/ATA chipsets also use this
same identification: Class MassStorage(0x08) Subclass SCSI(0x06)
Protocol Bulk(0x50). I've read nothing but complaints about this
driver, the issues it causes and the performance it lacks. One
individual reported 67% loss in performance. I know that I have
personally seen a drop in performance once I could use the driver.
I was about to submit a bug on one of the binary packages until I saw
this one tonight. Until this issue is resolved, 2.6.8 looks a lot better.
