RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Andreas Piesk 2011-06-21 15:24:15 UTC 
Description of problem:

this is my UMTS stick which worked in RHEL6.0:

  idVendor           0x19d2 ONDA Communication S.p.A.
  idProduct          0x2000 ZTE MF627/MF628/MF628+/MF636+ HSDPA/HSUPA

when i plug it in, it does not switch into modem mode.

"modem-modeswitch -v 0x19d2 -p 0x2000 -t option-zerocd" has no effect, although it executes without any errors. after looking through the udev rules i found two rules which seems to overlap:

in /lib/udev/rules.d/61-option-modem-modeswitch.rules:
ATTRS{idVendor}=="19d2", ATTRS{idProduct}=="2000", RUN+="modem-modeswitch -v 0x%s{idVendor} -p 0x%s{idProduct} -t option-zerocd"

in /lib/udev/rules.d/61-mobile-action.rules:
# ZTE MF6xx
ACTION=="add", ENV{ID_CDROM}=="1", ENV{ID_VENDOR_ID}=="19d2", ENV{ID_MODEL_ID}=="2000", RUN+="/usr/bin/eject %k"

especially the comment in 61-mobile-action.rules stating modem-modeswitch does not work for ZTE made me wonder. after following the comment by disabling the rule in 61-option-modem-modeswitch.rules the stick gets correctly initialized and works like expected.

Version-Release number of selected component (if applicable):

udev-147-2.35.el6

How reproducible:

always

Steps to Reproduce:
1. insert ZTE MF6xx UMTS stick
2. wait for initialization which does not happen
3.
  
Actual results:

stick does not switch into modem mode

Expected results:

stick switches into modem mode
