I have a Huwaei E353 USB device, which I use to connect with the tre.se
Internet provider. This device initially attaches as a mass storage
device with product id 1f01. Under Linux, it is then switched to HiLink
Ethernet mode with the usb_modeswitch program. OpenBSD 6.0 instead makes the
device attach as a umsm modem device (after initially identifying it as
a UMASS5 storage device), and I have been unable to connect
using ppp in that mode. Maybe the device is not supposed to be used
that way: AT^SETPORT=? does not even list modem mode as
available.
I made the following changes to src/sys/dev/usb/umsm.c, after the
settings in the device_reference.txt for usb_modeswitch (l 2632):
*** 704,709 ****
--- 704,711 ----
cbw.bCBWFlags = CBWFLAGS_OUT;
cbw.CBWCDB[0] = 0x11;
cbw.CBWCDB[1] = 0x06;
+ cbw.CBWCDB[2] = 0x20;
+ cbw.CBWCDB[8] = 0x01;
break;
case DEV_UMASS6: /* ZTE */
USETDW(cbw.dCBWDataTransferLength, 0x20);
After I recompiled the kernel with these changes, the device correctly
attaches as a cdce Ethernet device, and after giving the following commands, I
can use my Internet connection normally:
# ifconfig cdce0 up
# dhclient cdce0
So, these changes should perhaps be merged with the default kernel?
