I just got a Dell E6230 with the same E7 report: 73 03 0a
As noted above using the qemu serio logging doesn't work.
The driver only enables multitouch if it sees the right
name for the device in the DSDT.
The following patch (against the seabios in qemu-0.14.1)
enables the windows 7 driver (7.1211.101.114 from
http://www.dell.com/support/drivers/us/en/04/DriverDetails/DriverFileFormats/Product/latitude-e6230?DriverId=CKNFN&FileId=2988050063&urlProductCode=False
) to bind successfully and alows one to get data from the serio
logging patch
Are there any standard tools for reverse engineering the
protocol - I saw mention of an alps-reg-dump but was
unable to find it?
thanks,
James.
