Great News! Updating firmware of my ZTE MF636 to V1.0.4B11 (from V1.0.2B01) using a win-application from my local 3G data provider fixed all problems regarding instability of /dev/ttyUSBx creation/removal. Tested on Ubuntu 10.04 (2.6.32-29-generic #58)
Now I can use my ZET MF636 as expected! Note: after update usb-devices terminal command shows the following data T: Bus=01 Lev=01 Prnt=01 Port=05 Cnt=01 Dev#= 4 Spd=480 MxCh= 0 D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=19d2 ProdID=0031 Rev=00.00 S: Manufacturer=ZTE,Incorporated S: Product=ZTE WCDMA Technologies MSM S: SerialNumber=MF662_ZTED010000 C: #Ifs= 4 Cfg#= 1 Atr=e0 MxPwr=500mA I: If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.)

Sub=ff Prot=ff Driver=option MF662 appears in Serial# after firmware update (real model is MF636 bought before 3 years) If any other user needs any more tests, just describe the procedure.
