More.
I tried the same truss on the native machine, here the difference:
sonicle at nativeoi:/etc# truss -t stat,open tip /dev/cua/0
stat64("/usr/bin/tip", 0x0804794C)              = 0
open("/var/ld/ld.config", O_RDONLY)             Err#2 ENOENT
stat64("/lib/libc.so.1", 0x080470FC)            = 0
open("/lib/libc.so.1", O_RDONLY)                = 3
stat64("/usr/lib/locale/en_US.UTF-8/en_US.UTF-8.so.3", 0x08046BE0) = 0
open("/usr/lib/locale/en_US.UTF-8/en_US.UTF-8.so.3", O_RDONLY) = 3
stat64("/usr/lib/locale/en_US.UTF-8/libc.so.1", 0x08046AC0) Err#2 ENOENT
stat64("/usr/lib/locale/en_US.UTF-8/methods_unicode.so.3", 0x08046AC0) = 0
open("/usr/lib/locale/en_US.UTF-8/methods_unicode.so.3", O_RDONLY) = 3
open("/etc/remote", O_RDONLY)                   = 3
stat("/dev/cua/0", 0x08047B60)                  = 0
open("/var/spool/locks/LTMP.4182", O_WRONLY|O_CREAT|O_TRUNC, 0444) = 3
open("/dev/cua/0", O_RDWR)                      = 3
(...continues up to connected...)
Main differences are:
- stat of cua/0 returns 0 but the hex in stat is different (ending with 60 instead of 90).
- open of cua/0 retuns 3, instead of ENXIO

Wow...this is a very deep analysis ;)
Well, on the physical machine (where it works great), the device is very similar:
crw-rw-rw-   1 root     sys       99, 131072 Jun 21 17:33 modem at 0,2:0,cu
still 99....
On both my systems (physical and virtual) grep 99 name_to major gives:
usbsacm 99
then, on both systems:
sonicle at oi:/etc# modinfo |grep usbsacm
152 fffffffff7eaa680   4850  99   1  usbsacm (USB Serial CDC ACM driver)
and, on both systems, fmadm faulty returns nothing...
Please consider that the same USB CDC modem, is correctly seen by a Linux on the same VMWare,
using the same ESXi 4.1 procedure.
And...consider that plugging an USB key on the same machine, and making it available to OI from
ESXi 4.1, I can see and work on files with no problem....
Thanx for your precious analysis ;)

Hi Gabriele,
Some more steps to see what's going on. Are we talking to the right
driver? Is the driver loaded properly, is the driver configured
properly?
Following the path from tip to the driver:
So your tip error is:
open("/dev/cua/0", O_RDWR)    Err#6 ENXIO
# man -s 2 open :
ENXIO           The O_NONBLOCK flag is set, the  named  file
is  a FIFO, the O_WRONLY flag is set, and no
process has the file open  for  reading;  or
the  named  file  is  a character special or
block special file and the device associated
with this special file does not exist or has
been retired by the fault management  frame-
work .

Major number 99, minor number 131072? That's quite the minor number..
I'm not sure what your driver is supposed to be, but on my system it
would be wrong.
# grep 99 /etc/name_to_major
On my system its:
vgatext 99
vgatext driver does not seem right.... but that is on my system, what
driver is it on your system?
Substitute your driver in the following.
Then, is the driver loaded?
# modinfo | grep vgatext
Nope: Why not?
# grep vgatext /var/adm/messages
Nothing...
Try loading the driver.
# find /kernel -name vgatext
/kernel/drv/amd64/vgatext
/kernel/drv/vgatext
64bit?
# modload /kernel/drv/amd64/vgatext
any errors?
# grep vgatext /var/adm/messages
#  fmadm faulty
# modinfo | grep vgatext
291 fffffffff846f340   5070  99   1  vgatext (VGA text driver)
My driver loaded, did yours?
Find anything interesting?
