Bug 175379

After connecting USB card-reader with microSD card loaded, the red led
light turns on. Then I mount that drive. In dmesg I see:

umass0: <Generic Mass Storage Device, class 0/0, rev 2.00/1.00, addr 2> on usbus2
umass0:8:0:-1: Attached to scbus8

Files are read O.K. from SD card through that USB-cardreader. But when
I try to write some files on SD card, I get luck in much less than half
times. Small files (about tens of kB) are written O.K. But when I write
larger ones, the device turnes led light off, and becomes irresponsible.
Only "usbconfig reset" helps. But filesystem is wrecked and needs "fsck".
Dmesg output is as follows^

I have AMD-powered usb controller on motherboard:

kernel: ehci1: <AMD SB7x0/SB8x0/SB9x0 USB 2.0 controller> mem 0xfe5fa800-0xfe5fa8ff irq 19 at device 19.2 on pci0
kernel: ehci1: AMD SB600/700 quirk applied
kernel: ohci4: <AMD SB7x0/SB8x0/SB9x0 USB controller> mem 0xfe5f9000-0xfe5f9fff irq 18 at device 20.5 on pci0

Yes, on Windows there's no such problem as far as I tried.

How-To-Repeat: Use mentioned above hardware and try usage scenario.
