Hi Kay,

so I was playing with adding environment variables to devices in the
udev database for later easy enumeration. And I like having ID_VENDOR
and ID_MODEL available and would like to extend this even to PCI and
SDIO in the future, but why are all whitespace replaced with "_".

P: /devices/pci0000:00/0000:00:1a.1/usb3/3-1/3-1:1.0/ttyUSB0/tty/ttyUSB0
N: ttyUSB0
S: char/188:0
S: serial/by-path/pci-0000:00:1a.1-usb-0:1:1.0-port0
S: serial/by-id/usb-Novatel_Wireless_Novatel_Wireless_HSUPA_Modem_356846015115701-if00-port0
E: UDEV_LOG=3
E: DEVPATH=/devices/pci0000:00/0000:00:1a.1/usb3/3-1/3-1:1.0/ttyUSB0/tty/ttyUSB0

E: ID_SERIAL=Novatel_Wireless_Novatel_Wireless_HSUPA_Modem_356846015115701
E: ID_SERIAL_SHORT56846015115701
E: ID_TYPE=generic
E: ID_BUS=usb
E: ID_IFACE\0
E: ID_MODEM_GSM=1
E: ID_MODEM_PROBED=1
E: DEVLINKS=/dev/char/188:0 /dev/serial/by-path/pci-0000:00:1a.1-usb-0:1:1.0-port0 /dev/serial/by-id/usb-Novatel_Wireless_Novatel_Wireless_HSUPA_Modem_356846015115701-if00-port0

This is one of my UMTS modem sticks and the corresponding USB details
are this:

T:  Bus\x03 Lev\x01 Prnt\x01 Port\0 Cnt\x01 Dev#=  3 Spd\x12  MxCh= 0
D:  Ver= 1.10 Cls\0(>ifc ) Sub\0 Prot\0 MxPSd #Cfgs=  1
P:  Vendor\x1410 ProdIDD00 Rev= 0.00
S:  Manufacturer=Novatel Wireless
S:  Product=Novatel Wireless HSUPA Modem
S:  SerialNumber56846015115701
C:* #Ifs= 2 Cfg#= 1 Atr  MxPwrP0mA

E:  Ad(I) Atr\x03(Int.) MxPS=  16 Ivl\x128ms
E:  Ad‚(I) Atr\x02(Bulk) MxPS=  64 Ivl=0ms
E:  Ad\x02(O) Atr\x02(Bulk) MxPS=  64 Ivl=0ms
I:* If#= 1 Alt= 0 #EPs= 2 Clsÿ(vend.) Subÿ Protÿ Driver=option
E:  Ad„(I) Atr\x02(Bulk) MxPS=  64 Ivl=0ms
E:  Ad\x04(O) Atr\x02(Bulk) MxPS=  64 Ivl=0ms

So as you can see we are mangling the Manufacturer and Product
whitespaces into "_". Is there are specific reason why we are doing it
this way?

Regards

Marcel
