Billionton PCMCIA GPRS/GSM modem, PCGPRSQ-B, 0x0279, 0x950b, 0x8604da84

[Wladimir Mutel]

	Dear PCMCIA developers,

	One person asked my help on bringing up and making work his modem
	under Linux (Debian unstable, kernel 2.6.18.7, udev 0.105,
	pcmciautils 014). Everything was happening on the notebook Samsung P28,
	with Ricoh PCMCIA bridge RL5c475 rev.b8 at PCI address 02:04.0
	and PCI subordination {00-01-01, 00-02-06, 02-03-06}
	(pci=assign-busses did not help). This card is perfectly detected
	and initialized by Windows XP SP2 home edition running on the same
	hardware as standard PCMCIA modem with serial port (I can send you
	resource allocations that it gives to the modem if you want).
	Under Linux, however, pccardctl status shows that 5.0v 16-bit PC Card
	is in unbound state (however pccardctl ident shows that it has
	function 2(serial)). Module serial_cs gets loaded (by udev, I guess),
	but no additional ttySN comes up in dmesg (except a pair of notes
	about LSR safety check for ttyS1 which I expect to come up).
	The card is similarly unable to work under other Linux distributions
	(Mandriva 2007) on other notebook hardware (Acer Travelmate 2482)
	where Windows supports the same modem equally well. I can send you
	any further required information, as well as I am ready to follow
	your recommendation on checking and manually overriding
	my Linux system configuration and startup/module options,
	or redirecting me to the proper contact	persons and/or maillists.

	The problem is that this mentioned person lives in another city
	and we had met only for a short. May be we could interact with him
	by email as he is not very strong in English.

	Thank you in advance for your attention and help.
