Anyone successfully using CentOS 5 and a Keyspan USA-19HS USB-Serial Adapter?
by Barry L. Kline 26 Feb '09

26 Feb '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I occasionally need to connect to a serial device and in the past have used minicom and the Keyspan USA-19HS adapter. It has worked flawlessly. Once I upgraded, I could never seem to make this work. The kernel recognizes the adapter, it gets properly assigned as /dev/ttyUSB0, and minicom seems to transmit data to it (as evidenced by the green LED on the device that flashes whenever I hit a keystroke. The problem is, it never returns any data. If I use VMWare to boot up WinXP I can access anything connected to the adapter, but it grinds me to have to boot up 'doze for that purpose. This morning I ran into the problem again and did some googling to see anyone else had this problem. I found this entry in http://www.kernel.org/pub/linux/kernel/v2.6/snapshots/old/patch-2.6.20-git4… Date: Wed Jan 3 15:36:25 2007 +0100 fix for bugzilla #7544 (keyspan USB-to-serial converter) At least the Keyspan USA-19HS USB-to-serial converter supports two different configurations, one where the input endpoints have interrupt transfer type and one where they are bulk endpoints. The default UHCI configuration uses the interrupt input endpoints. The keyspan driver, OTOH, assumes that the device has only bulk endpoints (all URBs are initialized by calling usb_fill_bulk_urb in keyspan.c/ keyspan_setup_urb). This causes the interval field of the input URBs to have a value of zero instead of one, which 'accidentally' worked with Linux at least up to 2.6.17.11 but stopped to with 2.6.18, which changed the UHCI support code handling URBs for interrupt endpoints. The patch below modifies to driver to initialize its input URBs either as interrupt or as bulk URBs, depending on the transfertype contained in the associated endpoint descriptor (only tested with the default configuration) enabling the driver to again receive data from the serial converter. Greg K-H reworked the patch. Signed-off-by: Rainer Weikusat <rweikusat(a)sncag.com> Signed-off-by: Greg Kroah-Hartman <gregkh(a)suse.de> As you'll note, the keyspan stopped working at 2.6.18, which is the kernel used by CentOS 5. My question is whether or not this bug still exists in CentOS5 or if someone is successfully using the Keyspan with CentOS5. Thanks!

Create a Debian Repo Mirror

Anyone know how I can do this w/o rsync? We have a large mirror we made with wget, but I don't see how to prevent wget from fetching anything it has already? Thanks! jlc

Firefox plugins gone (but only for one user)
by Rob Kampen 26 Feb '09

26 Feb '09

Hi gurus I have a CentOS 5.2 current x86_64 that has Thunderbird and Firefox working well for one user account (my wife) but will not play nice for my account. I have uninstalled thunderbird and firefox (via yum) and re-installed - no change. I have just wiped the .mozilla folder and started afresh, but it still shows no plugins, yet the /usr/lib/mozilla/plugins/ has the libflashplayer.so link etc. How does all this stuff get hooked up. I have previously installed firefox direct from their site and not used the CentOS supplied rpm, but now that RH say the light and provides a current version, I use the yum process to get my firefox installed. Everything was working a week or so ago, but when I tried fixing things yesterday, all went rapidly pear shaped. In firefox I pressed the Check Now button under Firefox > Preferences > Advanced > System Defaults and now its gone and lost all my plugins Any idea how to get them back? Looking on the support.mozilla.com/firefox site provides little linux help and seems oriented to windoze users. Appreciate some insight from those who know how this distro hangs it all together.

(off-topic)Update sii-3512A serial ata controller - which flash memory?
by Marcelo M. Garcia 26 Feb '09

26 Feb '09

Hi. I had to update the BIOS of a Silicon Image 3512A Serial ATA controller. I'm not using RAID. When I run the updater program (updflash.exe), it asks me to choose flash memory from a list, something like: AMD Am29F010B (1 Megabit), AMD Am29LV01B (1 Megabit), etc. How can I find out which is flash memory of the controller? Thanks Marcelo

xen on CentOS 4.7
by Agile Aspect 26 Feb '09

26 Feb '09

Hi - has anyone gotten Xen on CentOS 4.7 to run successfully using Windows XP as the guest OS? I tried VirtualBox but it doesn't appear to work (at least for Windows XP) for a CentOS 4.7 on a Dell Precision WorkStation 390 (quad.) In fact, it pretty easy to crash the machine using the command line interface. There's blurb on the wiki Move a native CentOS4 installation into a Xen DomU but that appears to be Xen running on CentOS 5 install of Xen. I've installed the package kernel-xen. I'm new to Xen and I'm not familiar with the jargon. Any help would be greatly appreciated. -- Article. VI. Clause 3 of the constitution of the United States states: "The Senators and Representatives before mentioned, and the Members of the several State Legislatures, and all executive and judicial Officers, both of the United States and of the several States, shall be bound by Oath or Affirmation, to support this Constitution; but no religious Test shall ever be required as a Qualification to any Office or public Trust under the United States."

GNU Screen - emacs mode frustration
by Sean Carolan 25 Feb '09

25 Feb '09

I like Gnu screen, but the choice of CTRL-A as the command sequence is extremely unfortunate. Like many other bash users, I use CTRL-A to get back to the beginning of the line (emacs editing mode). How do you all get around this problem? Also, I'm wondering if there is an easy way to get mouse scrolling to work when reviewing terminal history in screen. It's a pain in the arse to CTRL-A then ESC to be able to scroll back.

Re: [CentOS] Python-MatplotLib
by Raghu Narasimhan 25 Feb '09

Dare I venture another query: I need to install python - matplotlib (pylab) on CentOS 4 with Python 2.4.6 (installed). Yum (with romforge) and/or apt-get isn't able to get anything relevant. Has anyone attempted this before? Even the offiical pages have no mention of CentOS. Do I need to add more to the repo file? I currently have base, update, addons, extras, centosplus, contrib.
