Hi,
I tried to look through archives - and I did not see the exact problem
that I am experiencing in there (although there might be some very
similar ones):
Also, this is my first post to the linux-usb groups and I tried to read
all the FAQs and hopefully I have all the information required to at
least give me some suggestions as to where to look next
OK, the details:
CPU: MPC8548E (with PCI1 & PCI Express support).
USB Chip (per subject line):
- NEC 720101
- Port 1 connected to external USB connector
- Ports 2-5 are not connected to anything & are
'logically disconnected" in hub driver.
EHCI Driver
Kernel: linux-2.6.23.8 (with one quirk found for this chip -
to select 48MHZ clock (it hung otherwise)).
I have no problems with loading the important modules (usbcore.ko &
ehci-hcd.ko (as well as the storage modules: usb-storage/libusual.ko))
for examples <from the syslog>:
hub 1-0:1.0: usb_probe_interface
hub 1-0:1.0: usb_probe_interface - got id
hub 1-0:1.0: USB hub found
hub 1-0:1.0: 5 ports detected

The problem comes with I put a thumb drive into this connector
connected to port1 (although when kozio diagnostics run - it works just
fine). Here are
