Hi All,
I use an AuthenTec AES2501 fingerprint sensor successfully from a
small application.
But when unplugging the device and plugging it back again,
it's not recognized anymore by Mac OS X (10.4.4).
Starting the computer again, it's all fine.
The system log shows the following:
kernel[0]: USBF: 17536.142 [0x36cbc00] The IOUSBFamily
is having trouble enumerating a USB device that has been plugged
in. It will keep retrying. (Port 2 of hub @ location: 0xb000000)
kernel[0]: USBF: 17538.674 OHCI driver:
OHCIRootHubPortPower bit not sticking (0). Retrying.
kernel[0]: USBF: 17538.674 [some more...]

kernel[0]: USBF: 17541. 74 [0x36cbc00] The IOUSBFamily
was not able to enumerate a device.
Do I have to write a device driver or can't I prevent the
IOUSBFamily from failing to
access the sensor? Or wait for an OS update?
