The format is: /dev/usb/X.Y.Z X is USB BUS Y is device index Z is endpoint 0xF The the usbconfig's dump_curr_config_desc which endpoint belongs to your driver. Also see the show_ifdrv command to see which driver is connected to which interface. I understand that. But I can't read

Repeat the same test using FreeBSD -current. a) On the machine where it is slow. vmstat -i ; sleep 1 ; vmstat -i interrupt total rate irq1: atkbd0 233 2 irq14: ata0 85 0 irq16: vgapci0

Re: Low perfomance when read from usb flash drive

I know that certain AMD USB controllers perform less with the new USB stack, but I've not been able to track down the issue. Yes, I have AMD platform (motherboard ASUS A8N-VM-CSM) Can you try another PC having another CPU brand? Yes, I have already posted the result - 22 Mb/sec, much better

Re: Low perfomance when read from usb flash drive

It might be a bug with your memory stick. Are your findings consistent accross other brands of memory sticks aswell, between 7.1 and 8.x ? Today, I tested another flash drive ugen1.2: USB 2.0 at usbus1 umass0: BUCK on usbus1 umass0: SCSI over Bulk-Only; quirks = 0x umass0:3:0:-1:

Re: Low perfomance when read from usb flash drive

Hi please explain what kind of test you have done. It's most likely not related to USB, but rather the file system. Maybe you can run the following test on Windows and FreeBSD to compare: dd if=/dev/da0 of=/dev/null bs=65536 I'm test on FreeBSD7-stable and FreeBSD-current and post results.
