Bug ID: 289986
Summary: ccde and-or rndis prevents my SIMCOM / QUALCOMM A76XX
to be recognized as a 4G/USB/LTE dongle
Product: Base System
Version: 14.3-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: usb
Assignee: [email protected]
Reporter: [email protected]
Hello.
I went rummaging through the electronic gadgets I purchased several years ago
and found the 4G/USB/LTE dongle SIMCOM / QUALCOMM A76XX.
https://forums.freebsd.org/attachments/dongle-sim-70-jpg.23800/
I want to try to configure it in FreeBSD for placing and receiving phone calls.
I will read docs,but at the moment I need some of your help to understand why
it disconnects in loop when I attach it on the USB port of my PC running with
FreeBSD 14.3...

Instead,it is well recognized by Linux :

cde and rndis sometimes conflict.. not sure if this is the case or if there is
a workaorund, but I found this :

(In reply to Bipin Chandra from comment #10)
It works on 12.1-RELEASE by kldunload if_cdce.ko, after the Zero has booted.
Patch does not seem to work :
Code:
marietto# kldunload if_cdce.ko
OK
but it still disconnects in loop :
Code:
ugen1.19: <ASR Microelectronics Arom Usb Boot Port> at usbus1
umodem0 on uhub0
umodem0: <ASR Microelectronics Arom Usb Boot Port, class 2/2, rev 2.00/0.00,
addr 57> on usbus1
umodem0: data interface 0, has no CM over data, has no break
umodem0: Can't setup transfer
device_attach: umodem0 attach returned 6
ugen1.19: <ASR Microelectronics Arom Usb Boot Port> at usbus1 (disconnected)
ugen1.19: <vendor 0x1e0e product 0x9011> at usbus1
cdce0 on uhub0
cdce0: <vendor 0x1e0e product 0x9011, class 239/2, rev 2.00/1.00, addr 58> on
usbus1
cdce0: No valid alternate setting found
device_attach: cdce0 attach returned 6
u3g0 on uhub0
u3g0: <vendor 0x1e0e product 0x9011, class 239/2, rev 2.00/1.00, addr 58> on
usbus1
u3g0: Found 3 ports.
ugen1.19: <vendor 0x1e0e product 0x9011> at usbus1 (disconnected)
u3g0: at uhub0, port 6, addr 58 (disconnected)
u3g0: detached
Everytime it disconnects,I can kldunload the module. Even this operation should
be done in loop :
Code:
marietto# kldunload if_cdce.ko
marietto# kldunload if_cdce.ko
marietto# kldunload if_cdce.ko
marietto# kldunload if_cdce.ko
marietto# kldunload if_cdce.ko
Sometimes it finds the module already unloaded...
Code:
kldunload: can't find file if_cdce.ko
but again :
Code:
marietto# kldunload if_cdce.ko
marietto# kldunload if_cdce.ko
marietto# kldunload if_cdce.ko
Code:
kldunload: can't find file if_cdce.ko
