Re: usb patch
On Sunday, October 30, 2011, Stephen Isard elucidated thus: I have an RCA VR5320 digital voice recorder. It has a usb connector, but isn't recognized by SL 5.6. I get log messages of the form kernel: usb 1-5: new high speed USB device using ehci_hcd and address 4 kernel: usb 1-5: ep0 maxpacket = 32 This is evidently a known problem and there is a patch for drivers/usb/core/hub.c with the comment A few devices (such as the RCA VR5220 voice recorder) are so non-compliant with the USB spec that they have invalid maxpacket sizes for endpoint 0. Nevertheless, as long as we can safely use them, we may as well do so. I think this patch is incorporated in 2.6.32 kernels. Q1: Am I correct in thinking that I would have to compile a whole new kernel, as opposed to just a module, to incorporate a patch to hub.c? Q2: Is there any sort of module or userspace hack I could try instead? I don't want to get into a position of maintaining my own kernel. I'd rather wait until I catch up with 2.6.32 and impose on friends with newer kernels or windows machines in the meantime. A1: Yes, it is a single module, but you'd need to pull the source from the new kernel, since it is a kernel module. You may be able compile it with the source of the current kernel, but since you're pulling from a new kernel, it might have dependencies in the newer kernel. In other words, you're welcome to try. A2: No userspace hack that I know of, as USB operations are a kernel- level thing. j -- Joshua J.

Re: request for package :: where to request?

Re: request for package :: where to request?
Hmm...I didn't see it in EPEL6, so I assume it was in Redhat now. That is odd. Hmm...cmake seems to be in SL6: http://ftp.scientificlinux.org/linux/scientific/6/i386/os/Packages/ Search for 'cmake' Version 2.6.4 Did you try yum install cmake ? j On Monday 20 June 2011, Adrian Sevcenco elucidated thus: On 06/20/2011 09:56 PM, Joshua J.

Re: Errors of instrument control with PyVISA in Scientific Linux 5.5
On Monday 23 May 2011, eigenroot elucidated thus: Hello everyone, I would like to control a Keithley source meter with PyVISA in the lab. The operating system is Scientific Linux 5.5, and the Python version is 2.4. I first installed NI-VISA's Linux package ( http://joule.ni.com/nidu/cds/view/p/id/2040/lang/en) which was compatible with Scientific Linux 5, and then ctypes from http://python.net/crew/theller/ctypes/ and linux-gpib from http://linux-gpib.sourceforge.net/. After everything was done successfully I fired up an interactive Python session, and typed import visa No errors. And then I typed keithley = visa.instrument(GPIB::25) but got errors: Traceback (most recent call last): File stdin, line 1, in ? File /usr/lib/python2.4/site-packages/pyvisa/visa.py, line 287, in instrument interface_type, _ = \ File /usr/lib/python2.4/site-packages/pyvisa/vpp43.py, line 777, in parse_resource byref(interface_board_number)) File /usr/lib/python2.4/site-packages/pyvisa/vpp43.py, line 398, in check_status raise visa_exceptions.VisaIOError, status pyvisa.visa_exceptions.VisaIOError: VI_ERROR_LIBRARY_NFOUND: A code library required by VISA could not be located or loaded. Could anyone please help? Thanks very much~! Is the library installed? Where is it installed? I've discovered that ctypes isn't always that smart. It might be looking for it in /usr/lib, but the library you want might be in /usr/local/lib, in which case, it might not be found. j -- Joshua J.

Problem using boot ISO
I downloaded SL-60-i386-2011-03-03-boot.iso today. The sha256sum checks out. I'm booting it in VMWare. It goes through its media check and says it's OK. Then, I get the message: The Scientific Linux disc was not found in any of your drives. Please insert the Scientific Linux disc and press OK to retry. Anyone have any ideas? I really don't want to download the DVD right now. :) j -- Joshua J.

Re: Problem using boot ISO
That is odd. Because, the ISO will give you the option of choosing Local CD/DVD when it asks you What type of media contains the installation image? Ah well, entering this URL: http://ftp1.scientificlinux.org/linux/scientific/6.0/i386/os/ as the URL for the installation image seems to be working now. A bit slow, but it seems to be working. :) j On Tuesday 17 May 2011, you said: I think I encountered that problem once. I believe I downloaded and tried that ISO thinking it would allow me to boot from a central server (over the internet) for the remainder of the files needed. Apparently it is used to boot and look on your local network for files in a specific location (for the Scientific linux disc). Urs Beyerle has a nice live CD that does the job for less than 700M. http://distrowatch.com/?newsid=06560 On Tue, May 17, 2011 at 6:01 PM, Joshua J.

Re: Problem using boot ISO
On Tuesday 17 May 2011, Jim McCarthy elucidated thus: I'm not an expert, but I believe the boot ISO is just that -- a bootable disk that is sufficient to initiate an installation, but not sufficient in terms of having all the RPMs needed for an install. In the past I've used the boot ISO only when doing a network install -- did you see an option for giving an FTP or HTTP internet location for all the RPMs needed for the installation ? I suggest looking at the on-line release notes / installation instructions for a network install. OK, that does clarify things. The readme says this: SL-60-i386-date-boot.iso Example: SL-60-i386-2011-03-03-boot.iso This is the network install and rescue image. This image is designed to be burned onto a CD. You then boot your computer off the CD I've not done a network install of an RH-derived distro for quite a while. A Debian network install boots up, starts the install, runs you through partitioning, etc, then finds a mirror and pulls down the packages needed for install. While you can add module to the installer at run time, it does not pull down an install image. Hope this helps, Yeah, it does. Just different worlds. :) -Original Message- From: owner-scientific-linux-us...@listserv.fnal.gov [mailto:owner-scientific-linux-us...@listserv.fnal.gov] On Behalf Of Joshua J.
