Hi Pablo,
Check out CR 6940972 "Unable to configure/attach USB Hub after power
loss" the title does not limit this to power loss scenarios.
On the Dell T310 system this was seen with the new Intel USB (ehci) as
well as other mother boards. Some of the USB ports were managed by one
chipset and others by this one. The issue for this CR comes down to the
chipset providing less information that it says it will be by a few
bytes.
This is to be fixed in build 139 which is not yet available for the
OpenSolaris. It is also scheduled for Solaris 10 Update 9 to be
available this fall (estimated).
No workaround for it until patch/fix is released in the build available
to OpenSolaris.org.
1. adding below lines in /etc/system
set usba:usba_debug_buf_size=0x800000
set usba:hcdi_errlevel=4
set ehci:ehci_errlevel = 0x4
set ohci:ohci_errlevel = 0x4
set kmem_flags = 0xf
2. When system boot up in good state, check with:
- output of "prtconf -D"
3. Pull out the power cable from the system and then boot it up.
- echo "::usba_debug_buf" | mdb -k > ./mistake_log.txt
- the whole file of /var/adm/messages
- output of "prtconf -D"
Things to look for from mdb output:
hubd1: hubd_get_hub_descriptor: length = 11
...
ehci1: ehci_check_for_short_xfer: residue=2 direction=0x100
ehci1: ehci_check_for_short_xfer: requested data=4107 received
data=4105
ehci1: ehci_check_for_error: Error 9 Device address 2 Endpoint number 0
ehci1: usba_hcdi_cb: ph_data=0xffffff014cc6b800 req=0xffffff017009aab8
state=2 ref=2 cnt=1 cr=9
Note the hub descriptor length is 11 but the cr=9 so only 9 characters
returned, short 2 from the expected 11. Also the requested data
determined from the HUB itself is listed as 4107 and the actual value is
4105.
If this does not match then setting the /etc/system parameters and
collecting the mdb output and open a new CR. Include the output from
the device driver utility as well if you can.
I hope this helps
