Dear all,

I have such an HSDPA card:

lspci -vvv
[...]
04:00.0 Network controller: Option N.V. Qualcomm MSM6275 UMTS chip
Control: I/O- Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-
Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- GSI 19 (level, low) -> IRQ 19
nozomi 0000:04:00.0: Nozomi driver nozomi_tty
Initializing Nozomi driver 2.21alpha (build date: May 9 2008 20:51:09)

And it stops... udev creates /dev/noz[x] devices but the driver doesn't seem to go over that. If I try to fire up Vodafone Mobile Connect Card Driver for Linux I have:

I suppose that these crashes are due to the use of uninitialized devices /dev/noz[x] while card still is in an initialization status. Should devices be enabled afterwards? What do you think could be the cause? I red something about 2.6.24 incompatibility with nozomi: do you know anything more?

Hi.

These error also occurs on 2.6.24-21-generic for 64bit. On 32bit system it works.

Is it planned to continue the development?

Hopefully,
Holger
