My tests say no. I can reproduce it on a 2.6.18-rc1, which didn't include the zd1211rw driver. It seems to be hardware-dependent. I can reproduce it on a x86/OHCI (SIS USB 1.0 controller rev 07), but not on a PPC32/EHCI (NEC USB 2.0 controller rev 04)). lsusb -v must run as root, because it appears the USB hub will not be accessed otherwise. A second lsusb -v hangs endlessly. The bug is always triggered on the "buggy" hardware. The events around the disconnect look like this: [ 217.532000] usb 1-1: rx_urb_complete() urb d52260a0 error -110 [ 217.532000] usb 1-1: rx_urb_complete() urb d5226160 error -110 [ 217.536000] hub 1-0:1.0: port 1 disabled by hub (EMI?), re-enabling...
