	That's a Ericsson phone, correct ? Check towards the bottom of
my web page for the workaround for buggy Ericsson phones. If it's not
an Ericsson phone, apply the same workaround and test.

	By the way, you are the first person reporting to me that the
VIA driver works, so it gives me more confidence on the driver.

	The first is a consequence of the stuff seen in the irdadump
above, so don't worry. The second as well, actually.
	For the third, I'll blame that on the phone, but it may be the
VIA hardware or driver.
