recluce said: No idea what package in Ubuntu is to blame here, but I have issues with my Huawei E220 (Vodafone) stick since the beta versions of Lucid. Unfortuntately, I cannot really test this, since I only use that stick when visiting Germany (a couple of times a year) and there are no obvious error messages.
In Jaunty (and early Lucid alpha versions): perfect function, storage device invisible, reliable fast connections
Since Lucid betas: stick is recognized, but storage device is visible. Connections are flakey, Ubuntu tends to "loose" the stick - so you need to disconnect and reconnect it to make it work again. Communication is much slower and there are frequent disconnects/reconnects. I verified that it was indeed the OS (and not network issues) by booting back into Jaunty, were everything worked as it should.
@phillw: I also tend to loose faith that any of the developers take regressions seriously, unless it bites them personally
if your modem is k3565
if so ,the vodafone Model {k3565} list on the system as E220 because of the ID's it gives, and is a known problematic device
this is how it goes
I have a vodafone k3565 ids 12d1:1003 so the system will see it as a huawie E220 E270
this device may be a E620 USB Modem true IDS are 12d1:1001
so depending on how it is configured it can present it,s self as two different modems
also it has different actions depending how it is switched , { number of ports and port sequence can vary }
this is not a regression as one may think , the kernels are improving at recognising more devices and act on the device id,
this a problem for the Huawie the services providers as regarding firmware and software etc , as to the ID's it presents to the system
there are instances of firmware upgrades changing the device id's of other models , and the only solution is to use usb-modeswitch
